The server returned an invalid JSON response.


PHP 7.3.11
Joomla 3.9.15
PHP upload_max_filesize = 200M
Image 44 kb

Thank you. Fixed an issue.

Hi!
apologies! I'm hijacking this topic because we experience the same error message, plus images don't get resized when uploading, since we updated to the most recent version of JCE just some days ago.
Could it be caused by the old php version we use on the server? (to be more specific: we're forced to use it, waiting for a server update)

JCE 2.8.5 Pro
PHP 5.6.40
GD headers 2.1.1-dev
imagick module 3.2.0RC1

And - if so - is there a way to get around this until we get the new server with php7x?

Thanks!

Thanks Ryan,

unfortunately the beta version does not solve the issue.
We are weiting eagerly for a php update on the used webserver. But that probably will take some time.

Thanks so far!

Hello,
I have the same with JCE Pro 2.8.6 RC3, Joomla 3.9.15 and PHP 7.3.9-1~deb10u1. Also, I done checking DB according https://www.robertwent.com/blog/fixing-json-data-errors-after-updating-to-joomla-3-6-3/. Still I receive „The server returned an invalid JSON response” when trying to upload files larger than 1 MB.

@Ryan It is possible that this is the reason, cause on another server where we have Imagick there is no such problem. I will talk to the administrator, thanks!

For anyones info i had this issue and in PHP Ini on my server i changed the memory_limit from 128mb to 256mb and the error went away
