#510 Internal server error after some actions

[exander]

I have Adminer installed on my server under nginx & php-fpm.

After some actions, for example creating new database, I get Internal server error (500) response, even though the action itself is unaffected, for example in this case the database is succesfully created.

This is what i get in browser (response has no body).

On server, there is no error in nginx error.log or php-error.log. Only in access.log I see that the URL (https://xxx.xxx.xxx/adminer/?username=&database=) vas visited and return code was 500.

There are like 20 other projects running on the server, no problem with any of them, so I am pretty sure it is Adminer problem.

And it is pretty anonying.

I have allso tried several Adminer version, all behave the same way.

I have been having the same problem recently. Simple inserts and updates will return a 500 error. I'm also using nginx+php. Executing the query as SQL will run fine, but if I try to edit a row with adminer, it will often time out.

I couldn't reproduce and there's not enough information about what could be possibly wrong.
