I'm going CRAZY because i'm uploading any CSS files (style.css from main theme, css from plugins, css from every single thing) over and over and they are old versions which don't refresh to changes (this have been happening some days ago, not sure when maybe 1 week ago or so, and i ended up realizing yesterday because i was focused editing other php files)but PHP files are updating instantly and without having to clear any kind of caché.
I've read so many questions/answers tutorials relative to this matter and is impossible for me to do it.
1.I'm 99% sure is not a matter of Caché. I have W3TotalCache and disabled it uninstalled and the issue stills there, i deleted/destroyed every single piece of cache in my browser, flush dns my connection, everything i try to access from other computers and happens the same.
2.I deactivated every single plugin i even deleted all the folders of plugins and restored them and happens the same.
3. I restored 1 by 1 every single file CSS & PHP file i modified from the original template, and happens the same.
4. I restored my .htaccess various times, happens the same.
5. Can it be a matter of FTP permissions?
6. Can it be my host? 1and1 is giving 503 errors and stuff this last week every single time someone logins, could it be related?.
This is incredible, how can this happen? There's no such logic.
I'm going crazy.
Apreciate any help.
