Likes Plus disappeared

[faliro]

Screwed up the forum a little, need some advice.

Can anyone help. After installing another mod (my 15th) - i lost use of the Likes Plus mod. It just disappeared from the forum.

So I went to uninstall the Like Plus mod and got this:



It basically says if I uninstall the mod - I could cause damage?

When I clicked on the failed file, I got this pop up:



Can someone tell me what is the best way to proceed? Should I delete/uninstall all the mods i installed today - and then deleted it this Likes Plus? Does it make a difference? What should I do? I am a new user and unsure how to proceed.

Cheers in advance.

You can revert the forum back to where it was prior to last mod install.  Package manager saves a backup in /Packages/backups before each mod install.  Download, unzip, upload.

Will it harm my forum simply to delete the Like Plus mod? I get the massive warning above when I attempt to uninstall.

[Illori]

you need to remove the code left over, you cant just delete any mod when it fails to uninstall cleanly.

Sorry I meant uninstall not delete. I assume if I just uninstall anyway it will remove all trace of the mod and thus solve the problem?

I read the link provided above - but that seemed to apply more to installing than uninstalling.

[Illori]

you still need to follow those steps in reverse to remove the code that is failing. if you dont you risk crashing your forum. you can NOT just uninstall and expect it to work correctly if it is telling you something is failing.

[faliro]

Final question (thanks for the all the help so far).

Is replacing the code with the forum's suggested code a good way to solve the issue - or could that corrupt something else?

Cheers

[Kindred]

you can't just "replace"

As the FAQ link tells you --  you have to manually parse the line.
If the issue is just that the white-space at the start of the lin doesn't match - then all is good, go ahead with the replace.

However, if the actual written code does not match the "before" bit (which is probably the case)
then you have to manually parse the code change and make the corrections by hand

I am completely new to this so I am researching the word parse from the link - the link which I have now read twice.

The fault as listed is this:



So it seems the replace is exactly the same at the 'find' minus the extra line of code below.

Sorry if this sounds completely stupid. I go to the index css or somewhere similar and add this line of code?

No problem at all, we will help you.

First of all, a simple line can alter a lot, so it doesn't matter, you should change it as well. Just navigate to the file where that line is placed (it should display the file where it's located right next to the button you clicked), search for it and replace it.

Thank you very much for this.

So it seems therefore I will simply be deleting a line of code in this case, correct?  Because I can see absolutely no difference in the first line.

[d3vcho]

Yes, you're right

[faliro]

Thanks a lot.

Found it and deleted it. There was some lines of script in between.. So I left them in place. Will wait for the forum to refresh to see if it worked.

[d3vcho]

I would suggest using a text editor (Atom, Notepad++, Sublime..) instead of your host's tool. It's better, but should work anyway.

[Kindred]

yes, that is correct. you did the correct action.

In this case, the auto-editor failed because another mod had inserted those lines of code in between.

The forum still reads exactly the same fault. Should I delete the code that is in between the code it told to me to delete and the code I was supposed to keep show here??

[Illori]

if a mod uses that code that is still installed, then no dont. just add the code in the correct location if you are reinstalling the mod. also be aware of where you are posting SMF likes plus is not the same as the mods support topic you were posting in.

You can revert the forum back to where it was prior to last mod install.  Package manager saves a backup in /Packages/backups before each mod install.  Download, unzip, upload. 

Remove the last mod as above, then you should be able to uninstall the Like Plus mod cleanly.  If you still want to use it, install it as the last mod, it will be easier to fix that way.  Right now you are tinkering with code that's been changed by two mods.

Yip. I have given it a day and I still have exactly the same error. So I am going to do your method today. I think I installed around 5 mods after this Likes Plus one and have no idea which one caused the conflict.

Just to be 100% clear - uninstalling Likes Plus with the error is dangerous? I will not be using this particular mod again I think.

Cheers again.

Install this which is a great mod for knowing which mods you installed when: http://custom.simplemachines.org/mods/index.php?mod=2323

- installing, or uninstalling ANY mod that shows errors is "dangerous"
However, it is not the fault of the mod. All mods which are approved on the SMF mod site have been tested to install and uninstall cleanly -- ON A CLEAN SMF INSTALLATION.

by installing *ANY* mods, you potentially add conflicts with installing or uninstalling OTHER mods.

The trick is to learn how to read the code changes and learn to parse them (as you did)
In your case, if you ran the uninstall - and then made the code change manually (or vice-versa) the mod would be properly uninstalled.
While what Sir Osis stated is true, it is not actually necessary... if you are willing to make one or two manual code changes.


I had a test site in which I installed nearly 200 mods. a few of them did require a manual update or two - but most of them were pretty clean (I never installed a mod that errorred in more than 4 spots and was still able to get almost 200 installed)

Thank you for this explanation.

If I now uninstall this mod - even though it still shows the error - is it now safe to do so seeing as I removed the offending piece of script?

On a separate note, when you uninstall a mod, are all the pieces of script associated with it removed from the CSS index and other indexes etc?

[Kindred]

yes. you removes the bit it is looking for, so it is going to show an error...  and yes, it will complete the uninstall if you now continue (because you have manually dealt with the error)

uninstalling mods should remove all changes that the mod made in the original installation. Yes.
It typically does NOT remove database changes and data.

Thank you very much.

Do I click on the option Remove all data associated with this modification:

[Steve]

Totally up to you. If you want the data removed that Kindred mentioned, then yes.

[faliro]

Totally up to you. If you want the data removed that Kindred mentioned, then yes.

The only reason I am asking is if there is any danger in removing all data associated with this mod.

[Illori]

if you dont want to use the mod again you can remove the data, if you are going to try to reinstall it at a later date then leave the data behind.
