Hello I have installed now after buying the last PRO version of GS Lodo Slider.
I created a page with just [gs_logo] and this is the result: http://agency.designexcellent.com/test-logo-gs/
This is how I configured the page: https://www.dropbox.com/s/82xwfu2e30k8cxc/gs.png?dl=0
My wordpress is Version 4.5.3 (last one)
Please let me know asap what’s wrong.
Thanks for purchase my plugin.
At Pro version of GS Logo slider, Logo height & width set to 200px.
Also, you can set different Logo height & width.
All logos height & width MUST be same as set at settings.
So please resize your logos larger than 200px or larger than which you set, then reupload logos from computer, NOT from media.
Hope this will solve your problem.
If still face problem, let me know & send your site access (if needed) @ samdani1997 (at) gmail.com
