Don’t get me wrong, I love WordPress, but as with any software it does throw up its share of issues. Most often, not with WordPress itself, but with the plugins, and specifically configuration of the plugin.
Here are some of the bugs we’ve come across and how we resolved them.
——————————–
W3TC Cache & Settings
Our problem was that the cache (which works really well) was building up folders sand files, so that we were getting Disk Usage Warning full messages.
This fixed it for us: The main thing is that Database Cache and Object Cache are disabled.
On shared hosting, these create a lot of disk I/O for no real benefit. It’s a different story for VPS/Dedicated servers, where those can really improve performance, but it’s just a bad idea for Shared hosting.

Thumbnail Width Problem with IE
In short, our thumbnails were displaying fine in all browsers except for Internet Explorer. In IE, the thumbnail appears as a thin slice. It links ok but looks strange because its not the right width.
How to fix the IE thumbnail width issue..
The problem is caused by this rule:
img, object, embed {
max-width: 100%;
}
or
img {
height: auto;
max-width: 100%;
}
Either remove the entire img setting or just this line [max-width: 100%;] from the CSS file, and then watch the image magically appear in IE.
Don’t forget to Ctrl F5 refresh..
Where is the CSS file, I hear you ask?
Easy.. Left side navigation = Appearance/Editor/ and there is will display the default stylesheet ready for editing.
Do a page search (Ctrl + f) and search for “max-width”.

Image Size Issue
While we are talking about images, a similar problem arises with IE7/8 with images not displaying correctly.
In the CSS file it says..
<img width=”100″ height=”200″
IE7\8 requires a measurement, in this case ‘pixels which is written as ‘px”. Change it to read:
<img width=”100px” height=”200px”
Don’t forget to Ctrl F5 refresh..

Rename Admin Login
I really like this plugin which dramatically hardens security.
Every hackers knows the login address of every WordPress web site = www.domain.com/wp-admin
This simple plugins enables you to rename the login address. Use with care, make sure you record the address of your new login.
Rename wp-login.php (unmaintained)
Change wp-login.php to whatever you want.
