Can’t Update slider

Dear roaasoloh.

Thank you for the question.

Please, deactivate all plugins and after that try to add a video again. Look after that you will be able to save the video in the slider.

If it doesn’t work out, please can you delete this code from all the files where you will find this code?

if (! current_user_can (‘manage_options’))
{
die (‘Access Denied’);
}

Please try and tell us know. We are waiting for your reply. Thinks your problem will be solved.

Thank You.

Hello,
The first trial didn’t solve the problem.
Please regarding the second part, the code, where should I search for, exactly, I mean what type of files it might be existed in.

Thank You

Dear roaasoloh.

Please, check all the files and delete that code from all those files.

Thank You

I found this:
if ( ! current_user_can( ‘manage_options’ ) ) {
wp_die( __( ‘Sorry, you are not allowed to manage options for this site.’ ) );
}

Is it the same!
I found it in several files like options-*.php

Sorry for this, you had to told me that I should check the plugin files to find this part of code,
even though I commented it /* */ but it didn’t work, and the same error still arises!!
would deleting it change thing!
I believe deleting or commenting is the same

Dear roaasoloh.

Did you delete the code from the all files?

Yes, I did, delete them all.
Same error: Forbidden
