Hi,
I have recently moved my OsTicket installation to a new server, and for now everything seemed to work fine, with the exception of the Audit Plugin. In fact, if I open a ticket and try to see the relative audit logs, or try to see the audit logs for an operator, I just get a blank window (see screenshots). 

I have tried reinstalling the plugin, unsuccessfully.
Thank you very much in advance for your help
Please find below the information on the installation:
OS: Linux
PHP: 7.4.10
MySQL: 5.7.32
OsTicket: v1.15.2
