 * Hi misterferguson,
 * Thank You a lot for using Daiva!
    It looks You use a plugin called “ergo7 surge”(
   or with similar name). I haven’t found any info about it, i think that is a plugin
   for Your earlier theme and that is not compatible with other themes. Please try
   to find it in Your admin’s plugin menu and deactivate it.
 * I hope it helps! Have a nice day!

 * Hi thanks for your reply, actually yes I found by myself that I had this plug
   in active and that’s why, but thanks again for your help I appreciate !
