Same thing here . . . kind of.
I reinstalled W3 Total Cache a few day ago, or maybe a little longer.
Everything seemed fine at first. However . . .
Today, for no apparent reason, when I tried to log into my blog using the sidebar login, I get a little pink box right above the login field which says “undefined”.
I wracked my brain out trying to figure out what was going on. I strongly suspected that the problem might be W3 Total Cache, because each time that I have tried to use or install a caching plugin, I run into major problems.
So, since I couldn’t even log in, I decided to manually remove the W3 Total Cache plugin, since the server machine sits right next to me.
Following the instructions on this forum, I manually removed the main W3 Total Cache folder in the plugins folder. I removed all of its related files from the wp-content folder. I removed its rules from my blog’s htaccess file. I removed both parameters that I had added to the wp-config file — one for caching, and one to increase WP’s memory to 64MB.
After doing that, I couldn’t access my blog AT ALL. All I got was an error message stating that there was an “error establishing a database connection”.
So, I reversed everything that I just explained, and now I can access my blog again, but again, I cannot log in. I get the little pink box which says “undefined”.
In short, I cannot even delete the plugin, or log in. 🙁
Worse yet, this is affecting another WP blog which is part of another domain that I run on the same server. I use MAMP PRO.
Even thought that blog does not even have W3 Total Cache installed, and never did, I cannot even access the blog, and am getting the same exact error regarding an “error establishing a database connection”.
Since this second blog never even had W3 Total Cache installed, this suggests to me that this plugin actually did something in the mySQL databases themselves. I don’t know what or where, and much less how to fix it.
Frederick, I gave your plugin a fair chance, and now it REALLY has me upset.
To reiterate:
1. With my blog, I cannot log in and get the pink box with the word “undefined”. If I remove all of W3’s parts, I can’t even access the blog and get the “error establishing a database connection” message. If I put all of the parts and rules back in place manually, it is back to the pink box.
2. With the second blog on the other domain, I can’t even access it at all. I just get the “error establishing a database connection” message.
Please assist at your earliest convenience.
Thanks!
