If this works, re-activate them individually (one-by-one) to find the problematic plugin( s). When you can’t get into your admin dashboard, try deactivating via [FTP or SFTP ](http://codex.wordpress.org/FTP_Clients) or whatever file management application provided by your [hosting provider](https://codex.wordpress.org/Glossary#Hosting_provider)( cPanel…). Also remember to deactivate any plugins in the mu-plugins folder (If you have created such folder). The easiest way is to rename that folder to mu- plugins-old. – If that does not resolve the issue, try switching to the unedited default Twenty Fifteen theme for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). When you don’t have access to your admin area, use [FTP or SFTP ](http://codex.wordpress.org/FTP_Clients) or whatever file management application your host provides. Navigate to /wp-content/ themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it. – If that does not resolve the issue, try [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F) via [FTP or SFTP ](http://codex.wordpress.org/FTP_Clients)or whatever file management application your host provides. Sometimes, an apparently inactive plugin can still cause problems. – If all the above steps do not resolve the issue, then try **MANUAL** updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old copies of files & folder on your server before uploading the new ones. Read the [Manual Update ](http://codex.wordpress.org/Updating_WordPress#Manual_Update) directions first. – **If you haven’t already done, always backup everything ( including your database) before doing any actions, just in case something really goes wrong.** * Thread Starter [bbb385](https://wordpress.org/support/users/bbb385/) * (@bbb385) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040760) * Can not login via FTP 🙁 message – Could not connect to server * Thread Starter [bbb385](https://wordpress.org/support/users/bbb385/) * (@bbb385) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040767) * but every few hours my site is back running, but when I try to do something inside it, like try to edit visual editor it crashes again ?! * [WPyogi](https://wordpress.org/support/users/wpyogi/) * (@wpyogi) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040768) * Ask your hosting company. * Moderator [t-p](https://wordpress.org/support/users/t-p/) * (@t-p) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040779) * If the problem is intermittent then it’s your server. What’s happening is that the web server and/or the database server are gettign overloaded and the connection is droping out or is refused for a short time. That gives you the database error as the website can’t connect to the database. To fix this, as [@wpyogi](https://wordpress.org/support/users/wpyogi/) suggested you’ll need to talk to your hosting company as they are the only ones that can do anything about hardware issues like this. * Thread Starter [bbb385](https://wordpress.org/support/users/bbb385/) * (@bbb385) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040784) * thx, I will try with them * [Vladimir Vassilev](https://wordpress.org/support/users/vloo/) * (@vloo) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040876) * Guys, check your database tables collations, as in my case it turns out that some are different from utf8 and my guess is that with the security patch in WordPress 4.1.2 they prohibit inserting invalid characters in the db. Most probably you all have utf8 in wp-config.php as encoding. Don’t change the DB_CHARSET constant, I’m still looking for a solution, but just have in mind that you all might be having the problem. * [Vladimir Vassilev](https://wordpress.org/support/users/vloo/) * (@vloo) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040878) * [https://core.trac.wordpress.org/changeset?old_path=%2Fbranches%2F4.1&old=32234&new_path=%2Fbranches%2F4.1&new=32234&sfp_email=&sfph_mail=](https://core.trac.wordpress.org/changeset?old_path=%2Fbranches%2F4.1&old=32234&new_path=%2Fbranches%2F4.1&new=32234&sfp_email=&sfph_mail=) * This is the patch that creates your troubles. * Current workaround is just to replace wp-includes/wp-db.php with the old one till a better (and safe) fix is at hand. * [stabakov](https://wordpress.org/support/users/stabakov/) * (@stabakov) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040890) * Thank you, Vloo!

It works. Let’s hope for a quick 4.1.3 update, fixing this… * [Vladimir Vassilev](https://wordpress.org/support/users/vloo/) * (@vloo) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040910) * 4.2 is coming in less than two days. It’s currently being discussed if 4.1.3 will be released before it with a fix, but it will be fixed in 4.2 for sure, as there is already a working patch 🙂 * [davek0974](https://wordpress.org/support/users/davek0974/) * (@davek0974) * [11 years, 1 month ago](https://wordpress.org/support/topic/update-412-problem/#post-6040935) * can this be the same issue i am suffering… * i have three WP installs, all were running fine until yesterday afternoon when that all fail with the same errors – the site has lost all media, pages, posts etc – the folders in WPadmin all show empty but the data is still on the disk. * Any data left on the site is all piled onto the home page, its a wreck on all 3 sites. * It occurred at at the same time i got the updated sites email so seems a strong coincidence. * Any ideas ?
