Upgraded Wordpress now server error 500

[Randall]

I just updated wordpress to 4.4 and now all of my LearnDash pages are coming up Server Error 500. I deactivated Social Learner theme and everything shows up OK. I downloaded the Social Learner, Boss , Boss-LearnDash and BuddyPress-Learndash themes and reuploaded them but no change.

Any ideas?

@vapvarun @pallavi is there a known issue causing this? My site visitors have been complaining about performance and we had a 500 internal server error for about 2 minutes yesterday.

Hi @apextraining, We have tried many times but the login credentials are not working.

We have created an account with username: buddyboss please upgrade it as an admin.

OK. So after the last disaster I had to recover my website. Now I’m back to page 1. Normal pages show but any lessons or courses come up server error 500. I think I’ve narrowed it down to W3 Total Cache. When I deactivate the plugin the courses/lessons show fine. I made sure that the Boss theme’s minify options were off. I still need help with this.

Hi @randall-league, you can keep Boss theme minify option on and turn off W3 total cache minify
I have enabled those setting inside your site , and also added _wc_session_ to bypass it from cache

Thank you for the help but I’m still getting the errors on the LearnDash pages. Are you not seeing them on your end?

Well, I should have checked before but it seems that when I am logged in I get a server error 500 but when I’m logged out I can access the page but even then the page seems odd. Like CSS styling is off.

Hold on a second, I think I’m getting closer to the problem. I’m guessing somewhere my w3 cache plugin, the theme and maybe my https plugin isn’t playing together.

Slowly working it out. It’s not the plugins, as far as I can tell. It might be some corrupted files in LearnDash.Dunno. But I’ve found some coureses/lessons/topics work fine and others don’t.

[Randall]

Any course that has more than 4 assigned lessons to it is basically broken. You can see the course page but if you click on the lessons you get the server error 500. If I dis-associate a few lessons to where that the course has 4 lessons, then like magic everything works. This behavior is with newly created courses or older courses. If I deactivate the Social Learner theme everything is fine. So somewhere the theme is at fault.

I’m not a programmer but I think its some kind of memory issue with the theme. I deactivated all of my plugins and everything was ok. Then start reactivating them one by one. Regardless of which plugin is activated , at some point the error 500 start showing up. It doesn’t matter which plugins are activated if too many are activated eventually I get a error 500 at some point. It might be the course page, the lesson page, or the topic page but somewhere the 500 pops up.

here is the error log

Hi @randall-league, I have added memory limit at your wp-config.php
and check multiple topic pages again , You server memory limit is 256MB
I have added a plugin to display your server stats in your dashboard studentcenter/wp-admin

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 1048576 bytes) in /home/***/public_html/wp-includes/post.php on line 435

Seems to be working now but another strange thing happened.

On Jan 3 , 10:41 somehow the same forum was created around 200 times. I have 17 pages of the same forum all created on the same date and the same time. I hope it doesn’t happen again.
