Form2Content 6.16.0
Form2Content SEF 1.0.0
Form2Content Anywhere Content plugin 2.4.2 /System plugin 1.2.1
The {$JOOMLA_ARTICLE_LINK_SEF} variable appears to be expanded in a bad plugin call. This is what I get
{plgContentF2cSef}11:hoeksche-waard,10:locaties%7B/plgContentF2cSef%7D
but it should be
{plgContentF2cSef}11:hoeksche-waard,10:locaties{/plgContentF2cSef}
For some reason, the curly brackets for the plugin close tag are rendered url encoded and not as regular brackets.
