WPML causes a fatal error on the page after restoring a backup

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client experienced a critical error on their website after restoring a backup from mid-December. The error was linked to the WPML plugin, which when disabled, resolved the error but removed the language switching option. Additionally, some products in the English version lacked size selection options, which were available in the Polish version.
Solution:
We recommended re-enabling the WPML plugins, including WPML String Translations and the WooCommerce Multilingual plugin, to address the critical error and restore language functionality. For the issue with product size options not appearing in the English version, updating the product from the default language (Polish) should resolve the issue. If the problem persists with other products, updating each from the default language is advised.

Please note that this solution might be outdated or not applicable to your specific case. If the issue persists, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying you have the latest versions of themes and plugins, and if necessary, opening a new support ticket at WPML support forum for further assistance.

You can also change the original language of page if you wish: https://wpml.org/faq/how-to-link-already-translated-pages/ Look forward to your reply. Thanks

tomaszK-61	The product updates really helped, thank you! I'm having trouble translating one payment method – bank transfer. In WooCommerce – Settings – Payments – Take offline payments – Direct bank transfer – the content is entered in Polish. Then I go to String Translations, but the Polish content appears as English there, and I can't add an English translation because editing is blocked. The only way to add a Polish translation is to add it, which is already there. I'm adding a screenshot. Could you please check this and set it up correctly?

tomaszK-61	Sorry to ask, but I've been looking for this option for a long time and maybe you can help. I want to change the link in the footer to the "contact" section in English. I once saw an easy way to edit it, but now I can't find it.

tomaszK-61	Hi, When I enter a translation on the same page, it still doesn't display correctly. Currently, the Polish version is fine, and the English version has a Polish title and an English description. Can you help translate the title "Transfer bankowy" to "Bank Transfer"? I'm adding a screenshot. Yes, I managed to deal with the links in the footer, thank you. I don't see any way in string language to translate "Rozmiar" ("Size") that appears in Checkout. Thank you Shekhar for your help so far!

tomaszK-61	Hi, "Bank transfer" is now displayed correctly. Thank you. The client was adding new products today, and all the links in the menu were working fine. Today, all the links in the product categories suddenly lead to pages with an "error page" in the Polish version. What's going on? I'm attaching a screenshot.
