Recently I decided to clone my existing website and move it to a subfolder, in order to make the second one in another language.
I’ve copied all the files to the subfolder, created new database, changed all the database links, modified htaccess and wp-config files – the “new”, copied website worked completely fine.
I decided to make the same change in both websites – logged in into the backend, opened the builder (yeah, I know, but I take my time to do it all by myself), and made exactly the same change on both websites (adding language bar above the menu).
What happened – on the main website, the language bar looks completely wrong (looks like no/wrong css – no background, icons without resizing etc.). On the new website (/pl/ subfolder) all looks good.
I opened the builder, couldn’t understand what’s wrong and simply saved the main website **without making any changes.** To my surprise – the issues somehow fixed on the main website, but without any reason, appeared on the /pl/ subfolder website that **I didn’t save.**
I decided to give it a test – I’ve opened the builder for the /pl/ subfolder website, and did the same – saved it without making any changes. And the miracle continues – the /pl/ website language bar issue somehow fixed itself, but it appeared again on the website, that I didn’t even touch this time.
How is it possible that an error moves from one website to another by saving the other one? Do I have some WordPress database issues, and what issues they can be?
