4.5 Update is Broken

Try deactivating all plugins. If that resolves the issue, reactivate each one individually until you find the cause.

If that does not resolve the issue, try switching to the Twenty Sixteen theme to rule-out a theme-specific issue (theme functions can interfere like plugins).

I switched themes and deactivated plugins, didn’t solve the problem.

The only place we are having problems are with the “Posts” and “Pages”, everything else is running fine (including Widgets and Media Library and images can be uploaded without any problems). It’s the buttons that aren’t functioning: Add Media, TEXT editor option, Add Tags, etc…

You need to figure out the JS error ??

Thanks for the instructions, if I am doing this correctly I have a couple of errors popping up. I’m not sure how to identify it though. I am getting the TypeError: e is undefined messages and Error: Syntax error, unrecognized expression: a[href=#toggle]
(I don’t have clue what what means)

But it definitely confirms my suspicions it may have had something to do with the script being broken.

EDIT: Ah I just realized I did Step #3 and I missed Step #2, but I don’t understand how to open wp-config.php. It doesn’t make any sense to me x___X||| Would you be able to explain it to me?

Hm, that’s close to https://www.ads-software.com/support/topic/read-this-first-wordpress-45-master-list?replies=7&view=all#post-8271654 but not exactly it.

Are you using the latest versions of your theme and all of your plugins?

Yes, I am using the latest version for everything.

Try adding define('CONCATENATE_SCRIPTS', false); to your wp-config.php file just below the define('DB_HOST' line.

To do so, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and edit the file with a plain text editor.

I’m sorry I have no idea what or where wp-config.php is. X_X; Could you please provide me more detailed instructions/explanation because I don’t get any of this stuff, it’s like a foreign language to me.

You’ll need to access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and you’ll find it in the same directory as the the wp-login.php file.

i have the same issue, and after turn on script debugging, i get this https://prntscr.com/as7zhy

So then it’s not the same issue. ??

Please open your own thread about that: https://www.ads-software.com/support/forum/how-to-and-troubleshooting#postform

I have the same issue. I click add media, and nothing happens. If I go to the media library, nothing shows. I can click an “add new” media button, and once I do, it opens a page with just a weird mode of the media manager, not showing any images, more of a text list. And text mode in the editor does not work.

Also, I went to the plugin editor to update all my plugins, and the “select all” button does nothing.

After manually selecting them all and updating, it looks like the media manager is working again.

Yes, per https://www.ads-software.com/support/topic/read-this-first-wordpress-45-master-list please do make sure that all of your plugins and themes are up to date before reporting an issue. ??
