On the “Sklep” page (polish language), I cannot switch to the translated “Shop” page. However, on the “Shop” page, I can switch back to the original “Sklep” page. I would like the language switch to work correctly in both directions.
In WooCommerce → Payments → PayU, the payment method texts are in Polish but show as English. When I change the language to Polish and click “Save,” nothing happens — the page refreshes, and the language still shows as English.
When switching languages on subpages at the bottom of the site, I get this error:
.../wp-content/plugins/wpml-string-translation/classes/MO/Hooks/LoadTranslationFile.php on line 82
Line 82 contains:
if ( file_exists( $defaultPathFile ) ) {
How can this error be fixed?
I have disabled error display on the site, but I have included all the issues I could see. In the debug.log, I only see:

WIth AI Chat i solved problem about translate payu. I need help with, change "sklep" to "Store"

Can you clear any available caches from the site and go to WPML-> Support ->Troubleshooting and click the below buttons:
+ Clear Cache in WPML
+ Set Language information
+ Fix element types collation
+ Remove ghost entries from the translation tables
+ Assign translation status to duplicated content
As for the errors, that’s fine, I’ll hide them since fixes are planned and they don’t affect how the site works. The only issue left is that I did what you suggested and the problem is still there. I even deleted the English “shop” page and created it again, but it didn’t change anything. Do you have any ideas?
What could be causing this situation where, when I’m on the English version, it correctly reads the translation and I can switch to the Polish “shop” page, but when I’m on the Polish “shop” page, I don’t have the option to switch languages?
To debug this issue further, I would need to check your site settings once, for this I would need temporary access (wp-admin and ftp) to your site.
So could you please provide me with those details, you will find the needed fields for this below the comment area when you log in to leave your next reply. hidden link
OMG, I made a backup and moved the site to another domain. The shop page worked fine there. I tried clearing the cache, but not the Redis cache at first. After clearing the Redis cache, everything started working properly on the main domain. Problem solved 🙂 Thanks!
