Front End bug after Jommla migration 3.3.4

Hello ,
I get a GMapFP Front End malfunction after a Joomla migration to release 3.3.4
When creating a new location thru the GMapFP module, it is impossible to validate the record.
The buttons "Save", "Save and close" and "Close" ar not working.
I have to go back thru the back arrow of my internet browser.
The GMapFP relase I use is J3.15F.

Any ideae of what happens? Is there a patch to download to correct this issue?
Thank you for your Help.
Roger

Thank you for your prompt reply.
Does the installation of the release J3_34F will impact the existing database?

Hi!
I have installed the new release GMapFP J3_34F and the issues is cleared.
The three buttons work now with Joomla 3.4.4
Thank you for your help very appreciated.
