404 Error While Updating Setting, Plugins, Accessing Plugin Settings Pages

Usually this kind of thing happens after making some kind of change. Have you changed anything recently?

404 Page not found – makes me want to think you should really go back and check those Permalinks again. something as simmple as a dash in the wrong place could cause that.

Try deactivating ALL your plugins, and reactivating them one at a time. to see if you still get the issue when activated one at a time.

Have you made any permission changes to your files or folders? Unix permissions often account for a lot of frustrations.

Does it still occur with standard ‘non-pretty’ permalinks?
What permalinks setting do you have set?

@jshaw5000 I just came to know that this is the permalinks issue and I am not sure if it has been caused by WP-Super-Cache. I just reset the permalinks to default and then updated the plugins and it worked fine When I set the permalinks to custom mode it stops working.

@Cubecolour My permalinks structure is /%category%/%postname%/

Shall I paste my .htaccess file here?

Shall I paste my .htaccess file here?

Probably not needed at this stage. Did you add anything to it manually?

Does the problem go away if you deactivate all plugins? If so you should be able to isolate the problem to one particular plugin by then checking if the problem still exists after enabling them one-by-one.

I don’t use WP-Super-Cache, but if you do isolate the issue to that plugin, tagging this thread with the plugin name may attract the attention of people with experience of it.

No, I did not make any changes manually to the .htaccess file but yes I am aware that wp-super-cache rewrote the file when I changed some settings.
No, The problem doesnt get resolved when I deactivate all the plugins.

Disable Supercache, and in your permalinks settings page save the options again as that will add the WordPress rewrite rules to your .htaccess file.

Try using Supercache in PHP caching mode instead as that’s 99% as fast as mod_rewrite caching and obviously easier to configure.

I tried using disabling and updating the permalinks after it. It still remains the same. Also when I click on Advanced settings tab of Super Cache it shows me 404 not found error. all other tabs are working fine

That’s bizarre. I don’t know what would cause that. You could try reinstalling Supercache, but I’m at a loss to explain why the settings page doesn’t work.

I Just figured out, it was conflicting with Bullet Proof Security Plugin and messed up the .htaccess file. I deleted everything from it and then reset the permalinks again. Now everything is back to normal. I truly appreciate your help.
