I am currently working on a school project for which I have created a wordpress website. Until recently my website aaerexpress.studenthost.me worked perfectly, but after updating to wordpress 6 I first had the bug that elementor stopped working and now my entire website started to stop working. When I want to open my website I only get this error text:
Fatal error: Uncaught Error: Call to undefined method WP_Taxonomy::reset_default_labels() in /home/vol14_4/studenthost.me/oosoh_31762467/htdocs/wp-includes/taxonomy.php:28 Stack trace: #0 /home/vol14_4/studenthost. me/oosoh_31762467/htdocs/wp-settings.php(402): create_initial_taxonomies() #1 /home/vol14_4/studenthost.me/oosoh_31762467/htdocs/wp-config.php(96): require_once(‘/home/vol14_4/s… ‘) #2 /home/vol14_4/studenthost.me/oosoh_31762467/htdocs/wp-load.php(50): require_once(‘/home/vol14_4/s…’) #3 /home/vol14_4/studenthost.me/oosoh_31762467/htdocs/wp-blog-header.php(13): require_once(‘/home/vol14_4/s. ..’) #4 /home/vol14_4/studenthost.me/oosoh_31762467/htdocs/index.php(17): require(‘/home/vol14_4/s..’) #5 {main} thrown in /home/vol14_4/studenthost.me/oosoh_31762467/htdocs/wp-includes/taxonomy.php on line 28

First, update WordPress manually.
There seems to be a problem updating.
WordPress Manual Update Guide
If your problem persists, first rename the plugins folder through the host. If it does not work, do so with the themes folder.
If the problem is solved by renaming the plugins folder, enter the counter and then go to the plugins section.
And then reset the folder name to the previous state.
All plugins are now disabled
Just activate them one by one
To find the problem.
The solution for me was to downgrade the PHP version on my cPanel.
For my case it was the php version, was running 7.4 and then downgraded to 7.3 and it all worked well after.
