Check your settings in your admin panel. Sounds like the function of moving to different pictures is working, but you don't have the option to show arrows (or something similar) set. I forget the actual designation, but what you are experiencing is one of the ways it can be set. Also note that the way(s) to close your lightbox are controlled in there as well. Based on the issues I have on my cell phone with zen lightbox, I like to be able to click outside of the image to have it close (I thought this will also force the arrows you are looking for).
The problem I described is that from my cell, if I try to zoom in the picture moves on the screen to somewhere to the side, and if I move the page around, the image also moves, so I can't "catch" the close button. Also, if I zoom out and try to click on the close button, my phone tries to zoom, so back into the same issue. But, there are key options also to move from picture to picture, which still work.
Thank you for the reply.
I went to the Control > Images and read every line.
I also went to Control > Fual Slimbox and read every line
I also went to Control > Zen Lightbox and read every line
I enabled the function of being able to close Lightbox by clicking anywhere on the screen. This is handy but when I checked out my website, I found out that the old issue of the default windows popping up re-emerged again. I should say the issue has resurrected. I again removed from the server and re-uploaded the file
/includes/modules/MY_TEMPLATE/additional_images.php.
That again cured the problem and now only Lightbox windows popup. I suppose this file has to be re-uploaded every time one changes Lightbox settings in the control panel.
However, and it the most important, I was not able to activate those move to the left and move to the right navigation arrows. I have not even seen a line that might be responsible for those arrows.
