Hi,

you mentioned that until last week everything was fine and without upgrades nothing can be added ( i.e fix this problem) this leads me to believe its probably an upgrade issue, WordPress 4.0 was just released.

Firstly i would deactivate all your plugins and see if that helps, if not then you might have a server side issue and it might help to contact your website hosting provider, if WordPress works fine after deactivating all plugins then its probably an update issue. After backing everything up, then i would go ahead and update everything, because your WordPress will be more secure and probably work better if you update.

Before you do anything I would suggest backing up your database, and wordpress files, and then i would update all your plugins and also update wordpress to WordPress 4.0, because on Thursday the 4th this week there was an update from 3.9.1 to 4.0.

If you are using any plugins that connect to an API such as Facebook or Twitter, then there could be some kind of conflict since WordPress and a lot of plugins have been updated in the last week. So what im saying is, even if you haven’t updated, all of this update business will still affect you, because your software is now out of date and may not be able to communicate with services that are expecting your WordPress and plugins to be udpated, deactivating plugins will help narrow this down.

Let us know how you go, with more info we can find a more specific answer ??

Hi I’m having a similar problem when adding new subsites, no new content is saved and it just shows a blank page. Are you using yoast wordpress plugin by any chance?

Have you tried:

• flushing any caching plugins you might be running, as well as server and/or browser caches.
• deactivating all plugins (yes, all) to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s). If you can’t get into your admin dashboard, try resetting the plugins folder by FTP or PhpMyAdmin (read “How to deactivate all plugins when you can’t log in to wp-admin” if you need help). Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old
• switching to the Twenty Fourteen theme to rule out any theme-specific problems. If you can’t log in to change themes, you can remove the theme folders via FTP so the only one is twentyfourteen. That will force your site to use it.
• manually upgrading. When all else fails, download a fresh copy of the latest.zip file of WP (top right on this page) to your computer, and use that to copy up. You may need to delete the wp-admin and wp-includes folders on your server. Read the Manual Update directions first.
