The stars above at Raings are not displayed, so no rating is possible.

Hello,
After I plugged in the plugin, there is a technical problem.
The stars above at Raings are not displayed, so no rating is possible.
I have approved the rating of guests (options).
Also, the delete key does not work when logged in frontend.
What can you do to solve the problem?
The site is a customer site, so I can only give you access to Joomla. Access data in the system. Please tell me what you have changed.


Thanks for the support
