problem after update

Try:
– switching to the default theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

– resetting the plugins folder by FTP or phpMyAdmin.

– re-uploading all files & folders – except the wp-content folder and the wp-config.php & root .htaccess files – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

– running the upgrade manually via wp-admin/upgrade.php

Hi esmi, thank you for your support!
I did this:
– renamed plugins folder
– tried to deactivte plugins but can’t do that
– tried to activate default theme
– renamed themes directory
deleted all files except wp-contet folder, .htaccess and wp-config.php
uploaded new files from the unzipped new version of wp.
The redirection didn’t stop ??

When did you last repair the tables in your database?

oh i think nevermind.. i try now!

repaired tables, tryed an aoutomatic update but the problem didn’t solve. now i have to go, later i’ll try again with manual upgrade!
thank you esmi!!

I did again all steps:
I repaired and optimized tables.
I deactivated themes and plugins.
I repaired permissions to directories.
Then i deleted old files.
I’ve loaded new downloaded files of last wp.
Then run the upgrade, then i’m redirected on home page. Then when i try to log into admin i’m again redirected to upgrade.
I don’t know what do!

I saw that if it try to deactivate plugins from admin plugin page the message says that plugin are disabled, but it’s not so. I saw also that if i write a new post and try to load a picture i get an error: there was an error while loading. Please try again later.

Do you have a recent database backup?

I don’t have a db backup.
I realized now that I was wrong before taking database to another site. I find that I can not modify the database tables. I can not fix them, enhance them, and delete them. I do not know what to hang. I’m triyng with phpmyadmin with the login credentials of the wp-config.

So you moved this database from another site?

no no, before i was optimizing tables in a wrong db. In the right db it seems i can do anything, only browse it.

You need to contact your hosts about this. It could well be the source of your current problems.

I just did it. I hope to resolve the issue. thanks for the assistance provided, I will inform you of future developments! thank you again.

The host solved the problem. Thank you esmi!
