We have just updated our community but the server give we back an error (please take a look on the attachment), we need help to fix this issue.

 

Many thanks

That's a generic server error. Look at the server/PHP error logs to find out what the real error behind it is.

That is coming from your server itself and is a lot like your check engine light on your car. It says something is wrong but not what or where. As terabyte mentioned, you need to check your server/PHP error logs to find the real error of this.

Thank you @teraßyte and @Jim M,

here is the log

Looks like one or more files are missing. Try reuploading the files to your server.

Thank you @teraßyte,

please can you help me to find the right folder?

I downloaded it from my suite but I'm thinking would be find it on the invision power site

 

Many thanks

You can upload the contents of the Ipb folder inside whatever folder/directory that you used to install Ipb and don't forget to select the overwrite method. 

As mentioned, please upload all of them. If you are missing one, the chances are you will be missing others

Thank you everybody,

we fixed the issue.
We have uploaded the right folder from client are and all seems work well!

The only thing we have to change are the themes and images

 

Glad to hear you managed to get the issue resolved
