Page Builder not working

Hi,

I have a problem with Page Builder – it suddenly stopped working. On existing pages the Page Builder doesn’t show up at all, while on new pages it does show but it doesn’t function. I am able to click on the Add Row button but when I set the width etc and I click on Insert nothing happens.

I tried reinstalling the plugin and it didn’t help. Also tried using multiple browsers. I am using version 10.2.2.2 with WordPress 4.7.2 Create theme. I am unaware of any recent update done, however it is possible that some other user could have done some updates.

Please, can you help me fix this problem as it is crucial for my website?

Thank you
