Step by step what I have done:
I installed WP on a subdirectory so that I could build a new site while the old one was still up. During this process, I may have changed the password to mySQL database because it looked like it was empty and WP required one to install. This seemed to go fine until an hour later I was getting Error establishing a database connection.
This first thing I did was call my hosting company. After the woman put me on hold for 10 minutes she came back and said the database is fine, contact a WP developer for help. (We just paid $75 for someone to fix a plugin problem that if I had done some research on, I could have fixed myself in 10 minutes or less - not interested in doing that again)
Now when I type in the site name I get a blank page.. however the subdirectory comes up with the welcome page for wordpress so something is working right there.
I've read through 15-20 fixes on other posts and haven't found a solution yet.
I checked the function.php for spaces at top and bottom (none)
I tried renaming the plugins folder
I tried adding define(WP_ALLOW_REPAIR), true; (it came out with all Okays)
I tried a few other things but nothing worked
Any ideas?
