do you have a link to site?

any caching plugins or redirection plugins?

This gives a 404 error: http://wilmington.crimeboard.org/index.php/forum/unit-182f

This link is still good: http://wilmington.crimeboard.org/index.php/forum/

I have no caching plugins.

I have Peter’s Login Redirect plugin.  I’ve been running that for quite some time with no problem.  I disabled it temporarily and the problem still persisted.

I tried deleting all permission sets, then reestablishing permissions.  No luck.

just noticed you said specific page… so not the whole forum??? just one forum/topic?? link to it?

Any individual forum gives a 404 now.  The list of forums is still OK, but now a dead end.

I can set up a GoToMeeting session or give you admin access if that would help.

I did try rolling back to the prior version of Simple:Press plugins: Subscriptions, Polls, and Plupload.  No luck.

so this was working?? what has changed on your site? wp update? any wp theme or plugin updates?

Yes, everything was working great for months.  I looked back through the updates, but didn’t find any potential culprits.  To be safe, I rolled back the SP plugins that I mentioned above, as they were the latest updates.

No recent wp update.  Only recent theme update was an inactive theme.

The only new ground that I covered recently was to add the two new User Groups in SP, and modify and assign permissions.  Could something in that area be the cause?

I have tried deactivating plugins that I know worked fine with SP, but no change, still the 404.  I found a support forum topic regarding a similar issue that attributed the problem to a corrupted options table.  See https://simple-press.com/support-forum/sp5-general-topics/404-errors-in-forum-and-topic-views/.  How might I find out if that is the problem here, and if it is, how would I fix the corruption?  I do have backups but would like to avoid losing however many days of data since the last backup with an uncorrupted table, if that turns out to be the issue.

Thanks for your help with this.  I’m running low on ideas.

I would highly doubt it… but ya never know… try repairing the wp options and sfoptions table via plugin or phpmyadmin… cant hurt..

OK, I’ll back up everything first, then try the repair.

Meanwhile, is there any debugging information in SP that would yield some clue as to why the 404 is occurring now?  Were you able to see the issue at the links I provided?

I did the repair on wp_options and wp_sfoptions.  Still getting the 404.

I also tried deactivating all the plugins that were added or updated within the last two months.  Still the 404.

I did a repair on all of the wp_sf… tables.  Still the 404.

It’s coming up on 2AM here.  I’ll check back for suggestions in the morning when I’m more suitably caffeinated to continue this.

A new day dawns.  Any suggestions as to what I might try next?

I did find a database error reported in the SP Error Log:

Might this be related to the current problem?

My users currently have no access to any forum.  This is a serious and time-critical problem.  The possibility of just such a scenario is what motivated me to select a paid forum plugin with support rather than a free forum plugin.  I appreciate your timely response appropriate to the seriousness of the situation.

the biggest is trying to understand what changed… things do just break out of the blue… usually its something that has occurred on the site…

doubted it was the db but worth the try…

have you always had the older style pathlinks style urls vs custom urls?  that is, with the index.php in the url?

btw, I am getting tons of these:

Notice: Undefined index: HTTPS in /users2/data/t/tutorsystems.com-39577/public_html/dev/wp-content/plugins/wordpress-social-login/includes/plugin.ui.php on line 39

when visiting your site…  also is there a forum set up?  are you sure your db restore worked?  I cannot see any groups or forums right now where I could yesterday…
