SOLVED: I think I solved it with a backup now, however i couldnt mark the post as solved.
After trying to change some of the code in functions.php the website gave a fatal error and is only accessible in recovery mode. There seems to be a problem with the woopress core plugin, but i can’t figure out how to solve the problem. I tried to add 2 functions to change the amount of columns on the product category pages in functions.php. Now that file seems to be empty, can you please help to fix the issue?
This is the error message:
Een fout van het type E_ERROR werd veroorzaakt op regelnummer 227 van het bestand /www/wp-content/plugins/woopress-core/inc/shortcodes/etheme_products.php.
