XF 2.1 HTTP 500 Error

Active member
Just wondering if someone has any ideas how to help. Basically my forums have been stable for years but yesterday I went in and changed some user permissions for forum access on a few members and now my website is crashing constantly with HTTP 500 errors... can this in any way be related?

Thanks

Shane
 
I cant get it due it to continually crashes... it lets me in but then crashes. Its like it is intermittent... so I get in am able to disable all add ons and themes then it crashes and I get back in again etc. Currently trying to reinstall forum software.

The rest of my hosting is fine.. its a xenforo error not site wide so I presume it has to be a problem on my end.
 
Hmmm I reinstalled the software and am now getting this when I try to run the install upgrade.

Ok so I got into the install bit... got this...

You are already running the current version (2.1.10 Patch 2). To do a fresh install, click here.

When I click rebuild master data I get this error.

Right... so I get the error 500... I continually pres refresh and once in ever 20 refreshes it lets me in... am I causing the overload on calls to the db?

Should I just walk away from it for an hour. :)
 
You've got something running that isn't closing the db connection when it's finished. Instead it's looping and opening up other connections and so on.

Quick fix but not ideal is to restart the server as that would stop whatever is running and causing the max out
 
I'd be more inclined to think it's something to do with this:

but yesterday I went in and changed some user permissions for forum access on a few members
and an issue with an upgrade that uses permissions which isn't closing down the connection once the changes were made ......

....but that's just a stab in the dark

Try turning off all add-ons, replicate the previous change, and see what happens.
If it works as it should, re-enable the non-permission based add-ons, and repeat.
If all's still good, re-enable permission based add-ons one at a time checking for errors - trial and error (excuse the pun)
 
If you keep getting "too many connections" errors you want to increase the value "max_connections" in the MySQL config file (my.cnf).
If your host doesn't allow that..you may need to change hosts.
