I've googled a bit, but didn't found anything.
As soon as I change language to German(upload german language files to wp-content/languages and add line in wp-config.php), front-end works great(everything is translated since I've translated the theme also), but when I try to go to wp-admin I'm getting this error:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 7680 bytes) in ...wp-admin/includes/class-wp-list-table.php on line 135
If I try to go to themes/new post etc I'm getting corresponding errors.
As soon as I switch back to default(english) language from wp-config.php, everything works perfect(except the website is in english ofc).
Increasing memory limit in wp-config.php doesn't help as well.
Any ideas ?
