XF 2.0 Forum Down! Adapter.php at line 121

[AudiTT]

Hi, i was using xf 2.0.1 and my forum went down with this message:
XF\Db\Exception: No such file or directory in src/XF/Db/Mysqli/Adapter.php at line 121

whats the problem?

This is happening when XF is trying to connect to your MySQL server.

If there have been no changes to the MySQL server or your config file to cause this, then we'd recommend that you contact your host for assistance.

i am running my own vpn, it is not managed,
another website (wordpress) is working just fine in the same place.

There's not really much more we can suggest. The issue is with the MySQL server not being able to connect. The "No such file or directory" error usually suggests the server is offline or that the mysql.sock file is missing. Sometimes you can get around that by using the server IP (likely 127.0.0.1 if it's on the same server) rather than its hostname (likely currently localhost, again, if it's on the same server). But, really, you'd need to troubleshoot what went wrong in the first place to ensure it doesn't happen again.

and if i try to visit my forum, i get http 500 error

 

[Chris D]

Your MySQL server is refusing the connection that XF is trying to make.

We’re not in a position to be able to provide advice as to why that is as the issue can only exist between XF and MySQL and there’s nothing we can do to impact that if MySQL is rejecting the connection.

I've found that this occurs when you accidentally forget a ' or " or < or > or something small in a php file somewhere.
