I have loaded a your demo, bicycle and i could before be able to go to the shop page and review and edit, then if you look at past ticket there was a problem on the home page and header, that a your colleague fixed.
then when i went back to the shop page or i try to edit with elementor a product page i get that error.
so there is something wrong there.
this is my problem. we have the elementor pro license.
also we have an issue because as suggested by yoru colleague, i have downloaded from you site the revolution slider plugin and reinstalled to latest version, however when i get and use it it says it is not registered, while we should have it as registered.
hope this clarifies the issue
