Hi  
can you switch your Pydio to debug mode so that we have more infos about the error ?  
See conf/bootstrap\_context.php  
Change this line to true: define(“AJXP\_SERVER\_DEBUG” , true);  
and then send us the stack,  
thanks.

Verify mysqli extension and enable it if it was disabled.

I’m getting this in Pydio core 8.2.5, was it ever resolved? Users are reporting frequent disconnects.
