Page/Post Preview Not Working

Have you tried:

– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the default theme to rule out any theme-specific problems?

– resetting the plugins folder by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.

– re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress?

– increasing your available memory?

Thanks esmi, I haven’t tried deactivating all plugins, I was afraid I was going to get that answer.

The phpMyAdmin link you gave me is instructions to deactivate ALL plugins it seems. How do I reactivate after that?

Make a note of the option_name value before you edit it. Then you can change it back again afterwards.

I reset the plugins through myPHPadmin, but I still have the same problem. This is the same thing as deactivating all plugins, right? So none of my plugins are the problem?

I’ve tried switching theme but didn’t work either.

As far as re-uploading WP – that would wipe out my theme and plugin files.. how do I restore them?

And finally the memory – that’s not the error I’m getting. How could it be related?

I didn’t suggest a complete re-upload. I suggested re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress.

And insufficient available memory can cause many different symptoms.

Ok now I’ve tried all of it.. increased the memory to 128M in wp-config.php, and uploaded wp admin and wp includes, still no dice. Any other suggestions?

Try resetting your custom permalinks back to the default setting.

Still no ??

Seems like when I try preview on already published posts, it goes to http 500 internal server error, and ones in draft stage go to my domain, but with a “That ‘something’ you are looking for isn’t here! We’re very sorry, but the page that you are looking for doesn’t exist or has been moved.” message on it.

I thought maybe it had something to do with the Super Cache so I’ve already manually installed it but still didn’t fix it.

If you have an .htaccess file in your WP folder, try renaming it.

What I meant to say is I’ve already manually uninstalled Super Cache.

What do I rename htaccess to? or does it not matter? and this would be the one in the main WP directory?

When you uninstalled the cache plugin, did you make sure that you removed any cached files or folders?

It doesn’t really matter what you rename .htaccess to. It needs to be the .htaccess file associated with WordPress. If you’re running WP in a sub-folder, look in that sub-folder. If you’re running WP in root (even if it’s installed in a sub-folder), you need to look in the domain root folder.

Yes I followed the manual uninstall instructions on the plugin. I removed the cache files, deleted the rewrite rules in htaccess..

the reason I asked is because I have several htaccess files in different folders.

I renamed the main .htaccess to .htaccess2 but still no.

When you get the “you are looking for isn’t here!” message, what does the url look like?

Have you tried contacting your hosts in case something has changed on the server? mod_security changes are notorious for fouling up WP.

The url I get is https://divabenefits.com/?p=1893&preview=true

The tech support on my host isn’t very smart, but I can ask.
