Hello I get this jquery error after my last kunena update to 3.8.10: "Uncaught TypeError: $(...).insertAtCaret is not a function". You can see the complete error in the following capture:
This error occours when users try to insert attached files to a kunena post. Attaching files does work good, but insert the file doesn't. I have checked a new template and this new template solves the problem. Obviously there is a incompatibility problem between Joomla 3.8.10 and my template. However, I would like to keep this old template, because it has a lot of customization I wouldn't like to lose. Could you help me to solve this jquery error in order to keep this template? I promise I will not update joomla for a long time :(
EDIT: more info, mi site loads jquery 1.12.4
