Rukovoditel Support Forum

I have 3 different reports showing on the dashboard. Every refresh some of them says: Error: 500 Internal Server Error
Internal Server Error
And when I refresh page again, some of those works and some other says Error: 500 Internal Server Error
Internal Server Error

Had this with 2.0 and now 2.0.1 same problem.

Please find php log on your server and attach here

My .../ruko/log directory is empty (according to Filezilla FTP client) or do you mean some other log?
server config is on dev mode.

Here is the entire error message:

Error: 500 Internal Server Error
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at ************* to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

Yes, I mean other log. This one is internal application log but if something is wrong and application is not working (like in your case) you have to check internal server PHP log. Each server have this log. Just contact your hosting support and ask them where you can find PHP log.
Usually it can be file error_log in document root. But can be in other place too.

Here is the java error

It's tell me nothing. Need php log.

I sent a request/ticket to find the php error log.
I also updated php from 5.6 to 7.1 and now I try if this helped. I will get back with the error log if i ever find that.
Thank you.

edit: php7.1 did not help.

For some reason I can't have error log but they replied this:
(Sorry in Finnish but Google translator probably can manage)

nuo virheet johtuvat siitä että CloudLinux LVE Managerin VMEM (Virtual Memory) raja ylitetään.
Muutin VMEM rajaa 1GB -> 1.5GB, ilmoittakaa jos virhettä edelleen tulee.

So this is just memory limit you your server that is why saw this error.

Now it works ok?

Yes seems to be working now. I had another installation on other web hotel but the same company and it had same issue.

Now both had this change from the server and now everything works:

CloudLinux LVE Managerin VMEM (Virtual Memory), VMEM limit from 1GB to 1.5GB.
