In my opinion languages messed up by Cloudflare. I use it some time before and it is good service but if cache only static content like images. Other optimizers/loader usually give unexpected results.
As I said, the problem was more than just translation. The layout was also messed up, including Category menus that were either missing or incomplete. Can you answer this question:
Can you tell me for sure that those problems were not being caused by the changes I made? Originally, I had the config file set to mysql, which was changed to amysqli, which was replaced with a new file provided by Abolabo. I need to know with a 100% certainty that this was not the reason for the problem.
PS: Website is slow again as I'm still using mysql instead of amysqli.
