Using RSForm! Pro together with the RS!Form Pro reCaptcha plugin stopped working, the reCaptcha does not show up in the form anymore.
Inspecting the page shows errors like “Unexpected token <” on line 2 and further down complains that RSFormProReCAPTCHAv2 is not defined.
The Unexpected token error is probably caused by a line in the <head> section calling a non-existing javascript (i.e. just links to the site root), like: <script src=”/?cc86e17febb09de1768c47283dc17a9b” type=”text/javascript”></script>. This line is originating from a plugin.
It turns out this is problem occured after upgrading to RSForm! Pro 2.0.12 and using the reCaptcha plugin.
The simple solution was to download and reinstall the current “Google No Captcha ReCAPTCHA 1.52.1” from the downloads section at RSJoomla (you might need to login to get to your memberships downloads section).
Note! Just using the Joomla Extensions Update to try to update the plugin will solve the problem. You need to download the plugin and install it.
