Problem with replacing new with old files

When the website start working, after replacing repeatedly times. The file that I submitted that's new version is in old version because the website wanted to revert it to a old version.

Might have been a bug with the upload because the server has been suffering some performance issues. Were you able to solve it? Which artifacts did you see the bug on?

The issue is that website taking so long to load, also. Did you migrate to CloudFlare? Also the comments section aren't working.
