This is Plesk bug with ID #PPPM-4284 and Apache ( 57968 ) issue; the fix is considered to be included in one of the next Plesk updates.
The following workarounds are available. Please choose one of them to apply:
1. Change PHP handler to FastCGI.
2. Recreate/rename the subscription with lowercase letters. The renaming can be done at Subscriptions > Example.com > Domains & Websites > Hosting Settings. Since direct renaming will throw a 'domain name is already exists' error, please use the following scheme: Example.com - Example2.com - example.com.
