OpenCart3 what to do if site changes are not applied?

Question

Twig

Guys, hello, help och urgently needed)) The situation is unique in its own way, I have already tried all the methods in the world and just give up. Changes are not saved in .twig They are saved in files at the root of the site, but are not applied to the site itself. Through the editor in the design, all the norms will be preserved. The cache has already been deleted just everywhere, it is nowhere left.
It seems to me that it all started with an error, in the morning I go to the site, and there are a number of warnings. It was written about the openBay and cache files. A little googling solved the problem - commenting out the line in Twig.php there is also related to the cache. Errors are gone, but now it looks like this.
Of course, I already uncommented this line to check if it was the case. But no. Now there are no errors and changes are not saved ...
I tried to put modules to clear the cache, but they just don't appear either. There is no interface for deletion, only in the list of modules and nowhere else.

Answer 1

The problem was in FTP access. Check if the files are being changed on the hosting itself through the panel, if they are not saved, then rewrite FTP access to the root folder)

Answer 2

The guys on Version 3.0.2.0 also encountered this problem, tried to edit footer.twig but to no avail, cleared the cache everywhere, changed the code on the server didn’t help, I didn’t find a solution on the Internet either, after a while I figured it out, it turns out I need more modify file here /storage/modification/catalog/view/theme/your_theme/template/common - there was another footer.twig the same in my case
