Hi Robbo and Billy
Apologies for the delay but there is now an update that should address the issues faced after updating to v4.4.
Where you previously used:
[infopopup:mytag]
You will need to change this (in WP4.4. and above) to:
[infopopup tag=mytag]
As the README states, we have already been informed that there may be an incompatability between this new version of the plugin and reCAPTCHA by BestWebSoft, which I will look into as soon as I’m able.
Other suggestions and feedback will be looked at in early 2016 when we will making the plugin a bit more full-featured.
Chris.
