Hope the title describes my situation.
I have an unmanaged VPS where I did the worst typo possible (chown -R username:www-data / <-- I accidently hit enter after that /
Anyway, I got everything working and I just went into my old servers mysql folder, copied just the database folders, and then added them to my new servers mysql folder. Everything seemed to work fine, all my sites loaded as they should and all the data from the databases transfered over.
But here is the problem: I cannot change anything. IE: If I go into Wordpress and create a new post, when I hit publish, it just sends me back to the posts page with nothing changed This same thing happens if I try to save settings, install new applications, etc. Anything that involves changing info on the databases.
I also have tried to make a new database and install vBulletin to it but it is having the same issue. However there is a whole bunch of "Deprecated" errors on the install page and this error also shows up after I try and go to the next page:
Warning: Cannot modify header information - headers already sent by (output started at /install/init.php:44) in /install/authenticate.php on line 55
And here is one of the deprecated errors:
Deprecated: Assigning the return value of new by reference is deprecated in /install/init.php on line 44
I've tried to search for answers but I don't really even know what to look for. I think the error happened when I was installing php. I first started to install php and fastcgi and installed it but when I tried to turn on fastcgi it gave me an error. So I decided to go to another tutorial (I am pretty newb at this stuff tbh. I completed pretty much everything on here using the vps bible if that helps) that was installed PHP-FPM (Separate) Installed from Source and everything installed fine there.
Thanks in advance for any help!
