Ever since we have been listed on the WordPress Consultants list, I have received a number of phone calls from panicked blog/web site owners regarding WordPress errors. Since I have seen a trend in the past month, I thought I would document some of the problems and their solutions.
Error establishing a database connection
Solution: The most common solution is to look and make sure you have typed in the correct user name/password/database name in your wp-config.php file. How can you check? Log into cPanel or Plesk, or directly to mysqladmin. Make sure that the user has the correct privileges to the database and that the password is correct. If you are unsure about the password, you can always delete the user and re-add them (remember to give the newly created user the correct privileges). If you are still having an issue, and you have a high traffic blog/web site, call your web host and see if you are maxing out the server connections – you/they might need to adjust their Apache/MySQL settings or you might need to start using WP-Cache to help control the connection issues. More than likely – you just entered in your user name/password/database incorrectly. This is by far the most common issue I have seen so far.
The default theme appears instead of your chosen custom theme when making CSS changes.
Solution: This is a known issue and hopefully will be addressed soon. If this happens, log into the WordPress Admin and choose your custom theme under “Presentation”.
You are not able to edit your widgets’ content using Safari
Solution: Grab the widget content that you want and drop it below or above another widget content box in the Widgets area in the WordPress Admin. Once you move it, the edit option will appear. Edit the content, and drag it back to it’s original location.
