Wordpress not updating cache
(The file name usually is at the end of the error message.) To fix this problem, you have two choices.
The easier choice, if you haven’t made any significant editing changes lately, would be to replace the file that’s causing the error message with your backup copy that was working correctly. Open the file in a text editing program that doesn’t create hidden characters; Windows Notepad is a great choice.
In Internet Explorer, hold down the Shift key while clicking the Refresh button.
Depending on your browser’s setup, though, these key shortcuts might not work.
You also can try visiting a proxy site, such as guardster.com, and load your page from there.
Otherwise, common problems that might cause Word Press to appear as though it isn’t loading or saving your changes include making sure that you’ve uploaded the latest version of Word Press and you haven’t make a mistake in the actual coding.
You might have to go through your coding line by line to look for mistakes.
We strongly advise you to try to enable upgrades via the Word Press web interface if at all possible.
