PDF file type is invalid

I’m not able to reproduce this issue. There is not any specific code the prevents the uploading of PDF files. The plugin uses the standard WordPress function for checking if the file is allow on your site. You can test if this is caused by Media Library Folders by deactivating it and upload the PDF file to your media library. Note that with Media Library Folders deactivated, the plugin will not be able to store the folder location of the PDF file.

These is a way to deactivate the test for allowed file types which is to add this line of code to your wp-config.php file:

define(‘ALLOW_UNFILTERED_UPLOADS’, true);

Hello,

I couldn’t upload the PDF via the regular media method. It errored with “Sorry, this file type is not permitted for security reasons”. But if I disable the MaxGalleria plugin, I can upload PDFs by either method. Is it possible that MaxGalleria is interfering? I assumed that these two plugins would work together since they are made by the same company. Thanks.

Which plugin do you mean? MaxGalleria is our gallery plugin for images and Media Library Folders is the one for uploading and moving files.

I am still unable to reproduce your issue even with MaxGalleria activated and I have searched the Media Library Folders code for anything that would prevent the uploading of this file type and have not found anything.

Hi Alan

Tested this situation, could not reproduce it also.
But when removing the file I get an error

My guess is that this is caused by the PHP version I am using on this site
MLF and MaxGallery is installed.

Ok, thank you Peter.

I first noticed the problem when using Media Library Folders to upload PDFs. Per your suggestion, I tested using the standard Media feature and got the same problem. I had recently started using MaxGalleria so I disabled MaxGalleria and the PDF upload issue went away. I don’t know why. I don’t know how to log to diagnose the issue. I can work around the problem by disabling MaxGalleria when I upload our newsletter once a month.
My hosting site just allowed PHP 7.2 (was 7.1). I switched but the issue persists.

All right. I am still not able to replicate this issue.

Hi Grezes71

Did you add the line define(‘ALLOW_UNFILTERED_UPLOADS’, true);
Into the WordPress wp-config file as Alan proposed?
It would be interesting to see if your problem is solved by adding this line
An other problem might be caused by the contents of the pdf file.
Could you sent an example pdf that does not work for you. We can perform a test with this file. Maybe it looks like a pdf file but it is not the proper format.
