I'm on Joomla 3.9.2 and PHP 7.2 and I use TZ_portfolio 2.1.2.
After this last joomla update, I had the following error message on the home page and the Portfolio page :
"Class 'TZ_Portfolio_PlusModuleHelper' not found".
I've found the related forum post and I did all the suggested updates (TZ Portfolio Plus - free and component : mod-tz-portfolio-plus-articles_module-package.v1.2.3). Then there where no error anymore, BUT the dedicated zone (module TZ Portfolio Plus Articles) on the home page as well as the Portfolio page (Portfolio - All article) are now displaying a white empty zone instead of the portfolio images.
So I tried to change the Media Type setting of a few Portfolio articles to "Image" instead of "No media", but there is still no image in the portfolio, juste an empty space.
Could you help me to resolve this please ? I've created you a admin login/pwd, but I don't know where to send it...
