When i desactivate the plugin my elementor work well but without the features of addons
Hi there,
Thanks for contacting our support 🙂
We’re so sorry for any inconvenience you had with the plugin. I will do my best to help you get this resolved for you ASAP.
Please don’t worry, this usually happens due to insufficient PHP Memory Limit or low Maximum Execution Time in your system. Please go through the instructions in the following link to fix that issue in your hosting account:
Editor Panel is Loading and Widgets Don’t Appear
Also, it’s important to make sure that your hosting account meets the minimum requirements:
System Requirements
Let me know if you need further assistance.
Best Regards.
Hi there,
Hope you’re doing well today 
I didn’t hear from you for a while, so I hope that everything is going fine with you.
Regards.
