Thank you, that was it but how it happened?
when i open page in developer mode, it founds 3 errors
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (tinymce.min.js, line 0)
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (plugin.min.js, line 0)
[Error] ReferenceError: Can’t find variable: tinymce
Global Code (post.php:1919)
How can i solve it?
Thank you for your comment, but i don’t have any plugins installed except Loginizer. Do you have any other solutions as it worked on 4.8.1
thank you!
