• TF Learn

Hi, I have experienced a problem from upgrading TF Learn from version 1.5.0 to 1.5.4

I first was alerted to the need to upgrade the extension, but clicking on upgrade leads to this error:
Impossible d'extraire le fichier com_tflearn_154.zip_dlid_1623766234_domain_japprendslaguitare.ca

So I went to https://labs.techfry.com/joomla/com_tflearn/extension.xml to collect the URL for downloading the ZIP file directly from labs.techfry.com

Installing from this URL gives me a bunch of warnings:

And now my courses won't display anymore - they are just blank.. 

How do I fix this course display problem? Thanks.
