The category-icons plugin is not compatible with WordPress 3.5 * See: [http://wordpress.org/support/topic/code-appearing-after-update-to-35?replies=5](http://wordpress.org/support/topic/code-appearing-after-update-to-35?replies=5) * Thread Starter [ichadwick](https://wordpress.org/support/users/ichadwick/) * (@ichadwick) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261545) * Fixed it by uploading 3.4.2 over top. * Will wait until the bugs are all ironed out before I upgrade toi a newer version. * Automatic upgrade SHOULD either warn users about potential problems first, or fix them. * Moderator [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261549) * Your bug probably was the category-icons plugin not being compatible with this new version. * > Automatic upgrade SHOULD either warn users about potential problems first, > or fix them. * WordPress warns you before an upgrade: “Important: before updating, please back up your database and files. For help with updates, visit the Updating WordPress Codex page.” * [rustyn](https://wordpress.org/support/users/rustyn/) * (@rustyn) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261552) * 3.5 is a train wreck. The link adds don’t work. I just lost an entire article when it froze trying to add a link. The link pop up showed up all the way at the bottom of the scree. Everything is moving in slow motion and erroring out. how do I get back to 3.4? I wish you guys would stop putting out updates every 5 minutes, especially when they are full of bugs which cost us hours of lost work and time. * Moderator [keesiemeijer](https://wordpress.org/support/users/keesiemeijer/) * (@keesiemeijer) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261554) * [@rustyn](https://wordpress.org/support/users/rustyn/) Please create your own topic * [rustyn](https://wordpress.org/support/users/rustyn/) * (@rustyn) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261557) * I don’t have time for creating my own topic. I’m too busy recreating all the work 3.5 just cost me. * [rustyn](https://wordpress.org/support/users/rustyn/) * (@rustyn) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261558) * That and I have no clue how even if I had the time * Thread Starter [ichadwick](https://wordpress.org/support/users/ichadwick/) * (@ichadwick) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261560) * Sorry, [@keesiemeijer](https://wordpress.org/support/users/keesiemeijer/), not only did I not see that warning anywhere, but it clearly is insufficient, since the problem was caused by a plugin, not the database. * Besides, a lot of WP users are not techies – they won’t know how to backup data or what to do when the upgrade crashes. * Perhaps updates should automatically disable ALL plugins, then let the user reactivate them manually. If there was a known problem about a plugin, shouldn’t it be noted SOMEWHERE on a screen so it could be dealt with BEFORE upgrading? * [docboulay](https://wordpress.org/support/users/docboulay/) * (@docboulay) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261662) * How and where do I get version 3.4.2 to upload it? * Thanks * Maurice * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261663) * > Perhaps updates should automatically disable ALL plugins * That would immediately cause major issues with caching plugins. Plus you’re assuming that all plugins are built to WPORG standards and can be deactivated. That’s not always the case, unfortunately. * **[@docboulay](https://wordpress.org/support/users/docboulay/)**: Do you have a pre-upgrade database backup? * Thread Starter [ichadwick](https://wordpress.org/support/users/ichadwick/) * (@ichadwick) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261675) * [@docboulay](https://wordpress.org/support/users/docboulay/): It’s archived on the WP site. I just used that version. * [rmacosky](https://wordpress.org/support/users/rmacosky/) * (@rmacosky) * [13 years, 5 months ago](https://wordpress.org/support/topic/wp-35-error/#post-3261680) * Ichadwick, were you able to reinstall 4.3.2 through the dashboard or did you have to do a manual install? If able to reinstall through the dashboard, please advise how.
