Hello,

I’m experiencing an issue with TranslatePress that only occurs when using a language other than the site’s default.

Here’s what happens:

When I log in while using a non-default language (e.g., my URL is mydomain.com/lt/login instead of mydomain.com/login), after a successful login I am redirected to the homepage, but the URL ends with #TRPLINKPROCESSED. For example:

mydomain.com/lt/#TRPLINKPROCESSED

If I log in using the default language, everything works normally (mydomain.com/), and no #TRPLINKPROCESSED is added.

Even on unsuccessful login attempts, if I’m using a non-default language, the login page refreshes and #TRPLINKPROCESSED is appended:

mydomain.com/lt/login#TRPLINKPROCESSED

I’ve tried the following troubleshooting steps:

Deactivating all plugins

Switching themes

Clearing all caches

It seems to be related purely to the login redirect handling with TranslatePress.

Has anyone experienced this or know how to fix it?

Thanks in advance!
