hi nursebibi, for your problem no 1, you can do this, on file named as section-heading-slider-fulltext.php
on line 30 – 33, remove the code.
for second problem, it bit weird for me, i try on my local to load your video, its loading fine. can you change file on folder jkreativ themes > public > js > internalmin > jquery.jcommon.js with this code : http://pastebin.com/YDnyAbMX
after you change the code, please let me know. i need to see js debug so i able to fix the problem.
