Site admin shows error after the recent update

Dear Booster,

After updating your plugin, the ADMIN area shows the following error. Please take a look. The front-end site is working fine. Only the problem occurs in the administrative area. I changed the directory name to make it disabled from the file manager and the site admin started working. When I activated it again, the following error came in.

Kind regards,
