Issue was with Incapsula (WAF) that was blocking /wp-admin/admin-ajax.php

Shouldn’t the plugin not be using a wp-admin module?

Hello, we have no issues with plugin version 2.2.6 and chrome.

However if we try to upload a file through Edge or Firefox we get the following error:

Hello, as stated before on staging it does not throw and java-script errors.

@boris – how would you like to proceed with this?

[impactechs]

I have restored the production website to the latest working version therefore you wont be able to check it. I could redeploy temporary if its needed.

Hello Boris,

There is something strange happening. On STAGING server everything works correctly.

On production when I am logged in as an admin and I try to upload a document it works.
If I am not logged in however I get the following error:

Uncaught SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

if(xhr.readyState == XMLHttpRequest.DONE && xhr.status == 200) {

    var response = JSON.parse(this.response); <--- this line

    if (end < size) {
        loop();
    } else if(response.success && response.type == 'file') {

Perfect – restored backup and updated all plugins with new version 2.2.6 and everything works properly. Thank you.

[impactechs]

The version I downloaded still says v2.2.6 which is the one I had installed.

Can you confirm that the files changed but the version remained the same?

[impactechs]

Any updates? its been some time now that this is not working.
