Same for my site also, which is using Wordpress.
While I am able to create new pages within Wordpress, I am unable to edit or modify existing content.
The Wordpress support forum has a number of posts with the same issues. Some ascribe it to a rule within the .htaccess file. Some ascribe it to wrong file permissions. Some ascribe it to a mod_security configuration made by the hosting provider, which detects a suspicious word or phrase within a page and blocks access.
There is no consensus on what causes the problem.
I have checked the file permissions. I have checked the .htaccess file.
All my existing pages cannot be modified.
Could the x10hosting gurus please look ito the matter?
With regards,
KP
