We made no changes in that area and have no other reports so somewhat puzzling…
The event will almost certainly be recorded in the php error log on your server. Can you take a look for any ‘fatal error’ entries? If nothing else is offered you can usually get to see the php error log via your hosting control panel.

as guests we cannot really look at your site…  but nothing jumped out… after trying Andy’s comments maybe go to forum – integration – page and permalink and try loading the forum js in the footer…

also, is your wp theme up to date?  wp does change versions of jquery and jquery ui which you theme seems to use… so it will need potentially need periodic updates as well…

Hi @yellow-swordfish  Here is a sample from the error logs. HOpefully this will be more informational to you than it is to me! 😐

well, its a database error… but its coming from another plugin… one called new user approve… does that ring a bell??   perhaps its not updated to work with current version of WP?  there have been some breaking changes in wp for new users (email, pw and such)… so perhaps an update is needed?

Can you disable the plugin and see if it functions with it disabled?

Hi Mr Papa,

Thank you for your support. I have disabled the plugin (which has not been updated in 11 months), but the the login functionality still doesn’t seem to work. The WordPress theme appears to no longer b supported which is not great, but we’re no longer seeing anything in the error logs except this error, which is not firing for login attempts, but is there in the logs so I thought I would share it with you so you can see:

[Thu Sep 01 14:40:48.860873 2016] [autoindex:error] [pid 20161] [client 66.249.79.49:61342] AH01276: Cannot serve directory /nas/wp/www/sites/wfaexlgl/wp-content/themes/persuasion/images/assets/: No matching DirectoryIndex (index.html,index.cgi,index.pl,index.php,index.xhtml,index.htm) found, and server-generated directory index forbidden by Options directive

I will create a user account for you to do your own testing in case that will help.

Please note that as this is a live client site, I have re-enabled the New User Approve plugin.

Well this new error is coming from your theme. I myself am not an expert on this but it looks like it might be suggesting this is a server setting of some kind. I would send that error to your host support to see if they can shed any light on it.

also, please note the message at top of forum currently… will be the weekend before we are able to look at this in depth…

Just guessing, but has your forum page somehow been changed?

I assume /community is the WordPress page for your forum. Possibly go to > forum > integration > and regenerate your simplepress url.

Also try running database repair from > toolbox > housekeeping.

Hi all,

Thank you so much for your assistance.

@fidosysop-2 , I tried the regenerate URL suggestion – I thought that was a really good one. I also tried the usual WP Permalinks re-apply trick, which has solved many problems with other plugins in the past. Unfortunately in this case, neither worked.

I didn’t quite follow your instructions about database repair (coudln’t find any sections with that name), but I did try clearing many of the caches on the page you referenced. For fear of breaking something, I did not try rebuilding any database tables.

What did solve the problem, was chatting with our upstream hosting provider. It turns out that their (seriously) awesome security measures, which do wonders for our clients overall, were interfering with the login functionality. Once they disabled a group of those, voila!

Again, thank you guys so much for your help. We chased this issue all the way down the line and unfortunately as you know you just have to diagnose and test until you find the broken link in the chain. I appreciate so greatly your patience and your input. Thanks once again!

Wow – after all that! The important thing is, of course, that it’s no longer a problem – so a good ending!
