Add New page becomes unresponsive using Dynamic Multi Level Fields plugin
I'm using Dynamic Multi Level Fields plugin with my Classipress classified ads site. When adding a new listing, after filling in the information and uploading the images, I click on the "Continue" button and nothing happens. Usually the button would change to "Processing". After waiting for 20 seconds, a message pops up saying "The following pages have become unresponsive." And the Add New page is indicated. The message continues, "Kill the pages" or "Wait". I wait for another 10 seconds and the finally the processing continues and I'm able to add the new ad listing. A person would not normally wait this long, especially not knowing that it will eventually allow you to move forward. I tried reducing the number of Country/Stare/Province/Cities in my list, but did not work. What could be the solution for this? Thanks.
