Blank Page! URGENT

[carbo92]

Hi all, I have a big problem with my website in practice this is already the second time that I do not charge more the site showing only a blank page. I tried to disable all modules but nothing. 

I asked the hosting and they sent me the following log, you could kindly help me? 

Thanks in advance to all:

 

If you take a look at the error_log file located inside the domain's folder, you will see the following errors:

It seems that while editing the template it became corrupted and now it is failing the execution.
This is either caused by a failing module or a corrupted template.
Unfortunately we don't offer support for these situations as they require an expert in PrestaShop to find out what was damaged and fix it.
We recommend that you try to find help at the PrestaShop support forums or try to undo any changes that were done, including the installation of any extra plugins or software.

As last measure, we could revert your account to the status it was last Sunday (Sept 21) when the system created a backup of it.
