Changes in WordPress are not being saved. I modified the homepage, clicked "update", wait. When the page is refreshed, it says at the top "Page updated" but the information at the bottom is unchanged.
I ran the WordPress database repair program, but no tables were corrupted.
I tried to install wp-optimize, as perhaps that would help optimize the tables and remove junk. I was able to install the file, but when I click on "activate" the plugin is NOT activated. It remains in the unactivated state.
What could be the problem and what could I do to fix this?
