Fatal error in module file

[Templo Gourmet]

Hi there,

 

While using a module that I have never used before (columnslider) from a third-party template, once I am configuring it the icons of the back office disappear (I attach a screenshoot). Furthermore, when I try to delete one slide of that modulo it gives me the following error:

[PrestaShop] Fatal error in module file :/home/*****/public_html/*****/classes/db/DbPDO.php:
Call to a member function rowCount() on boolean

I did some research and people said that it was caused because of the table 'ps_smarty_lazy_cache' did not exist but I have checked it and it does exist so I do not know what to do. I have already contacted my server provider and they say that everything is correct with them. Furthermore, I tried to reinstalling the module and everything remains the same.

 

I hope you can help me,

 

Thank you.
