I have not edited any core files.
I have tried to disable all my plugins, even moved them from the plugin directory to see if there is a conflict. No luck.
I have tried to use different themes. No Luck.
The only way that I can edit posts/pages is if I highlight the text that's in the post (see screenshot).
I've added a few jquery scripts to my themes header.php file, tried to take those out as well, didn't work. Tried switching themes, didn't work. The only theme file that I've touched otherwise was functions.php.
I'm working on a local machine using WAMP.
Any help would be appreciated, THANK YOU!
