Due to necessity to move it, I exported and restored the db via PMA. Now the public side of the website works, but on every page when I click on "history/view-source" a red Error page is shown. Same thing when I edit a page: the edit page with the page text is showed but error occur when I try to save.
If I try to run update.php this is what I get:
MediaWiki 1.33.0 Updater
Your composer.lock file is up to date with current dependencies!
Going to run database updates for wikidonca-wiki_
Depending on the size of your database this may take a while!

About 40 days ago I encounter a similiar error when I upgraded to 1.33 that I solved with a little of work running several times "update.php" meanwhile I was cleaning user/actor tables from deleted users (spam accounts registered and blocked in 2016) that were generating errors in migration between tables.
How can I solve now? If can be useful to know, I ran deleteoldrevisions.php before to get this error.
Hope someone can help me, inside this website there are 11 years of "work", please.
