The login to the WP-site does not function any more

[saint_malo]

good day dear community,

The login to the WP-site does not function any more - i have changed the passwd in the backend - but as for now the login does not work any more.
could it be that i have to

_ try out to switch off all the plugins (one by one)
_ try to look for the cache of the browser or the server
_ thry to set the themes_ back the site is runnig on

btw_: atm i do not have access to the backend of the DB - but if i have such - i will have a closer look at the tables

is ther any thing i could do more here - and now !?`

look forward to hear from you

Do you mean user logins for everyone, or just the admin login for you? Might be a caching issue...

might be a crush caused by newly installed plug-in if the log-in site showed 501 errors. You can change filename of 'plug-in' in cpanel-file manager-public-wp content into 'plug-in temp' and test again. If then you can log-in, you may need to check one by one see which is the exact plug-in caused the error and had it removed.

It sounds like a common WordPress login issue that can happen due to plugin conflicts, caching, or database-related errors. Since you don’t currently have DB access, here are a few steps you can try right now:

Disable plugins manually:
Access your site via FTP or File Manager, go to wp-content/plugins, and rename the folder (e.g., plugins_old). This will deactivate all plugins and help you check if one of them caused the issue.

Clear browser and server cache:
Sometimes caching plugins or CDN (like Cloudflare) can store old login sessions. Clear all caches and try again.

Switch to a default theme:
If possible, rename your active theme folder under wp-content/themes — WordPress will fall back to a default theme like Twenty Twenty-Four.

Check .htaccess file:
Rename it temporarily to see if corrupted rewrite rules are blocking login.

Once you regain DB access, you can also reset the password directly in the wp_users table or verify the siteurl and home values in wp_options.

If none of these work, try enabling debug mode in wp-config.php (define('WP_DEBUG', true) to identify PHP or plugin errors causing the login failure.
