Hi @davidecatalano74 again.
We sincerely apologize for the inconvenience. First of all I want to say that our plugin works great with the latest version of WordPress 6.1.1. You can see this screenshot if you want: LINK Our plugin is working on the latest version without any problem. And we tested it very well. We checked it on two live servers and did not find any errors.
There may be something else causing your server error 500, which is conflicting with our plugin or may be not. It can happen in various ways, Corrupted or broken .Htaccess file, permission error, third party plugin or theme, memory limit. We suggest you deactivate all your plugins then activate your default theme and then activate Eventin. And it is better if your server max_execution_time is 600.
After doing this, if your site is not working properly then we have to check your site.
And if we can’t investigate well, it will be very difficult to give a solution to your problem. Can you please check our PIN post and reach us so that we can investigate more on your side?
Hope you understand
Regards
