Preview problem when posting

[Valtam]

Hi everyone,

We currently have a strange issue with Preview. I have searched through the various threads here already, unfortunately we still have no solution. When a user goes to Preview on the first post, it takes them to a new page where you can see the Preview, so that bit is fine. If they then edit their post further on the new page and click on Preview again, it hangs on 'Fetching preview...' endlessly. The website is here - https://www.linuxliteos.com/forums Thank you.

Rather than going through heaps of things, trying to figure this one out, you might want to have a look at THESE, because this seems to happen quite a bit. Usually, because of some mod, or a bad bit of coding that's been added.

I see that you've posted here, too:

Does that mean that the problem only happens if you use that theme? If so, that post would be better than this one.

[Valtam]

Thank you for your reply. The Preview problem is not theme specific, that initial thread assumes that it could be, but I can confirm that the issue is on Core as well. I have read through numerous 2.x.x threads, it is a common problem unfortunately.  I am happy to provide a test account if someone more experienced than myself would like to see what is going on with perhaps Firebug or some other tool. This I'm afraid, is beyond my ability to debug. Thank you.

re. error-log - where is this located?

[kat]

Believe it, or not.... Admin>Error log.

[Valtam]

More specifically, found it under Admin, Maintenance, Logs, Error log. There are no errors there that I can see that relate to this.

[kat]

What I'm finding odd, is that it works the first time, yet doesn't on the second one. That really is kinda weird, that.

I wonder if the cache has been corrupted, somehow? Have to your tried clearing that, in the "Forum maintenance" section?

Maybe, even, tried renaming the cookie, in "Server settings"? (You'll be logged out, probably)

[Valtam]

Under Maintenance I have run all tasks:

Check all files against current versions
Result:
SSI.php    2.0.4    2.0.7

was the only outstanding result there.

All other tasks run, Preview issue still there.

[kat]

I really don't know what else to suggest. Did you try renaming the cookie, in "Server settings"? (You'll be logged out, probably)

Yes, I did thanks.

[kat]

OK... We have to be detectives, now, I guess....

I assume that everything worked, fine, until just before you posted, originally. Between the time that everything was OK and when it went weird, what did you do? Install a mod? Edit some code, or anything?

[Valtam]

Could I uninstall all of the mods, then test Preview? Then enable each one, one at a time?

[kat]

Or, just uninstall each one and test it. Might be good to read my sig, first, though.

[Valtam]

Are you able to debug this for us, with a test account?

[kat]

Not really, coz we won't be able to see any more than you can.

But, if you create one and post the details, anyway, someone might have one of those "AHA!!" moments, if we're lucky.

[Valtam]

Even with something like Firebug, it won't help you?

[TheKnown]

try going into your site error log, this can be found in cpanel  -> error log and see if anything is listed in their.

the alternative is to download fresh files from the 2.0.7 upgrade pack, uninstall all mods upload the fresh files and install each mod one by one again see what one causes the issue, but try first option first.

also backup the files before doing the alternative.

using firebug will not help all that much.

[Valtam]

Found the culprit, it was the WYSIWYG custom editor SCEditor4Smf 0.5.1

[meemzo]

I'm hoping the original poster or anyone else can help me with this issue.  I too just installed SCEditor4Smf 0.5.1 and the same preview thing started on my site.  I uninstalled at but it is still happening.  I assume from the changes it made to one of my files.  Anybody else able to solve this issue if they had it?
