Can't Edit Pages/Posts After Upgrading to 4.3.1

Does the error persist only in a certain browser?

No. I have tried Internet Explorer and Firefox. I also tried to access it on my phone. The edit text box is completely blank.

Try seeing if there are any errors in the “Console” of your browser; https://codex.www.ads-software.com/Using_Your_Browser_to_Diagnose_JavaScript_Errors

I’m having the exact same issue.
I noticed some JS-errors which is likely the issue:

Failed to load resource: the server responded with a status of 403 (Forbidden): /wp-includes/js/tinymce/wp-tinymce.php?c=1&ver=4205-20150910

It seems my /wp-includes/.htaccess is the problem. If i remove that, everything works perfectly!

Anyone know a fix to the problem?

Heeiii…

I’ve got the issue here. I can’t put a content into my post or edit my previous post. I can put a title or a picture but not the content. Like there’s no cursor to put on it.

I try in my ipad and mac, the result is the same. Is there any bug on the updates?

Thanks

Andrew – I am trying to follow the instructions that you sent me to diagnose JavaScript errors and I am stuck on step 2. I don’t even know how to access the wp-config.php file. Please help. I need something more basic with step by step instructions.

That’s okay, just open up the ‘Console’ for now. If you use Chrome, all you have to do is right click on the page and select “Inspect element”. Then press on the “Console” tab that pops up. Then try to replicate the issue and see if any errors show up there

I downloaded Chrome so that I could do this. One error is showing up.

Uncaught TypeError: Cannot set property ‘onPostRender’ of undefined wp-tinymce.php?c=1&ver=4205-20150910:21

The second line is a link (https://christchildsocietyofpittsburgh.org/wp-includes/js/tinymce/wp-tinymce.php?c=1&ver=4205-20150910)

Do you have any idea what this means?

Try deactivating all of your plugins to explore whether any could be responsible. If none are, keep all plugins deactivated and switch to the Twenty Fifteen/ Fourteen theme to see whether it could an issue with your theme.

The theme was the problem, switching to Twenty Ten resolved the issue. Thank you so much for your help! I really appreciate it!! I am trying to help a local charity with their site.

You’re welcome. Do you know where to go for support for your theme?

No, but that is ok! I am loving the new theme and will just work with it.

Similar problem. No ability to edit pages from the WordPress Dashboard in Safari.
Ran SCRIPT_DEBUG by following instructions here: https://codex.www.ads-software.com/Using_Your_Browser_to_Diagnose_JavaScript_Errors which fixed the error.

BUT…now I don’t know what I should do with the “define(‘SCRIPT_DEBUG’, true);” code. If I remove it, the problem persists. Do I just leave that code there?

Thanks for your help.

I know this is an older post, but I’ll post my solution as it is different than the others and none of the solutions here seemed to solve my issue. this solution does not involve adding code to the wp_config file. In order to do this you must have access to the WordPress database.
step 1. locate the WordPress database and the wp_users table.
step 2. locate your user within the table and note the user_ID
step 3. locate the wp_usermeta table. In the table locate the record with your user id and the meta_key ‘wp_user-settings’
step 4. change this value from ‘editor=tinymce’ to ‘editor=html’
step 5. save change, reload admin portal on wordpress site.

You should now be able to edit content on the page.

Can’t edit either visual or txt after 4.5.2 update. Tried most ll the ideas expressed above to no avail.

Frustrated!!!

Saw a similar thing on another of my sites and fixed it by getting everything moving quickly in the am.

It’s almost like the editing part of the “input post box” is waiting on the something elese the site to load and function!

Any suggestions?
