5.3 throws an error

OMG, i almost have had a heart attack.
Gutenberg throw me an json error and stuck my server side of that website. I couldn’t even check as a root in my own server what was the issue. In php throw 4-5 errors with different system files, the website was not working at all. No error 404, nothing, just blank page.
I did not even had a recent backup of server. I managed somehow to install another php version as a root of my server and then i could switch that website to use older php version, so i could get login as a admin on my website, and when i loged, the front end of website was still blank and unresponsive. I managed to switch themes, then deactivate all my plugins. Only then my site was back.
So, to conclude.
If you get any JSON error and website is dead, try login in backend, switch theme to another theme, then disable all plugins and reinstall your theme and plugins.

@deleyna Working now . Thanks for your help
any update regarding OceanwpExtra fixing, please share @deleyna @120filter @mailajoeyy @veso_peso @sam1215

Thanks, @veso_peso for the tip, it saved me from a lot of trouble. Ocean extra is an important part of my blog, disabling it is not a good solution.

I have the same problems ;(

etSkin::feedback($string) should be compatible with WP_Upgrader_Skin::feedback($string, …$args) in /home/onlikubd/public_html/wp-content/plugins/ocean-extra/includes/wizard/classes/QuietSkin.php on line 12

Same problems here but with a different plugin (Klarna)…

What do you think if I don’t do anything but wait for new update of plug-in. WII this problems be solved after updating?

Thx @veso_peso works it!

I had the automatic update of wp on two websites with the ocean extra plugin. At the login-administrator attempt I read the error Warning: Declaration of QuietSkin :: feedback ($ string) …. this caused blocking of access to the websites.
With ftp access to the QuietSkin.php file and its modification I solved the problem. Thanks a lot @veso_peso.

I disabled Ocean Extra. the site is working fine now. so what is the next step? Should I keep waiting for the fixing the issue or updating? or what to do? sorry guys I am newbie to wordpress. thank you for your help.

Hello,

following this topic as i do have the same problem! There is a general problem with OceanWP. Luckily I only have only 3 from their paid Plugins installed. But they are not working anymore either! I had to do a workaround as my menue was gone also ;-( Kept me half night. Not happy ….

Let’t hope that OceanWP sorts that out quickly!

Same issue. Already thought the rest of my day will be a clusterf*ck on steroids when heaven sent me the patch from
@veso_peso. Thank you very much!

@miroslava22 @chewiewithme
@veso_peso solution. It’s easy. Login to FTP and edit the file QuietSkin.php

A quick fix is to change the following line (line 93) in wp-content/plugins/ocean-extra/includes/wizard/classes/QuietSkin.php:
Replace

public function feedback($string) { /* no output */

to

public function feedback($string, ...$args) { /* no output */
