Media Manager >> Upload >> Select a 45Mb MP3 file, then get:

The server returned an invalid JSON response.

php >> post_max_size = 256M
php >> upload_max_filesize = 256M
php >> memory_limit = 256M

Global Profile >> Editor Parameters >> Filesystem >> Upload file size (KB) = 130,000

What should I look for?

In the file browser the screen shows:

Drop files here

doc,docx,dot,dotx,ppt,pps,pptx,ppsx,xls,xlsx,gif,jpeg,jpg,png,webp,apng,avif,pdf,zip,tar,gz,swf,rar,mov,mp4,m4a,flv,mkv,webm,ogg,ogv,qt,wmv,asx,asf,avi,wav,mp3,aiff,oga,odt,odg,odp,ods,odf,rtf,txt,csv files up to 126.95 MB in size

Thanks for the help.

Figured it out - for anyone else...

Check the File Name.

The file name on the local drive had an apostrophe in it.


Jason error



I"m not seeing an issue with apostrophes in file names in my tests. JCE will remove them from the file name as they are invalid, but it could be that another process on your site or server is generating the error when encountering the apostrophe.

Just because you're not paranoid doesn't mean everybody isn't out to get you.
