 * Hi [@alexia078](https://wordpress.org/support/users/alexia078/)
 * At first, thank you for choosing our theme and service.
 * 1. The reason for the issue can be your installed plugins, please deactivate 
   them one by one and you will able to catch the which one was the source for the
   issue.
 * 2. If you want to not lose all the changes made with the plugins, please install
   3rd party plugin staging, clone your website database and make the changes on
   the cloned staging site, here is the video guide to better understand how it 
   works [https://www.youtube.com/watch?v=YtY-q5BBpeE](https://www.youtube.com/watch?v=YtY-q5BBpeE)
 * Kind Regards
