Alerts 404 error

[Chyandour]

I'm getting a 404 from links to posts in Alerts. The posts exist if I search for them, but the link in Alerts to new posts or replies always goes to a 404.  Any clue as to a possible cause.

Can you check the links from your alerts, what do they look like, is there anything odd about the links?

The links should look like this I think
(links below are to imaginary content, and the last one should give an error if clicked here):

- To view all alerts https://www.simplemachines.org/community/index.php?action=profile;area=showalerts
- To view a specific alert https://www.simplemachines.org/community/index.php?action=profile;area=showalerts;alert=12345;
- To view the post directly through the link in the alerts list https://www.simplemachines.org/community/index.php?topic=12345.msg12345#msg12345

Many thanks for the reply.

The Alert URL looks like this: https://reformpartyforum.uk/general-discussion/just-a-test-593/new/index.php?topicseen#new [nofollow]

The https://reformpartyforum.uk/general-discussion/just-a-test-593 [nofollow] part of the URL takes you to the topic OK, so I guess it's the /new/index.php?topicseen#new part that's causing the problem.

I have tried uninstalling the mod and removing the data, then reinstalling, but no change.

looks like a problem with pretty urls

Many thanks, you are correct.

Uninstalled Pretty URLs deleting data , and Alerts 404 problem went away, all Alert URLs worked. Reinstalled Pretty URLs and the problem returned. So I guess Pretty URLs and Notify Board Reply mods don't play nicely with each other.

Pretty URLs is a must, so I guess Notify Board Reply has to go.
