Please check the image I posted (it is from your online live preview).
The glitch is also in your demo! (go to “work” and click the first image).
The enlarged image and text description display behind the thumbnails; you cannot read the text or view the full image.
Here is the link to my test site: http://www.palletcover.co/_solotrio/index.html (go to “products” and click the first image).
Sorry, but i can not see such issue on demo site using Firefox, Chrome. Can you let me know which browser you are using? Also make sure you are using the latest version of template as this bug was resolved in a later update after initial release.
Sorry, but the demo is using the latest version of template which do not have this issue. I see your template have old version source HTML, which if you can change to latest version then you would be good to go.
You can download the latest version of template from your Theme Forest Downloads page.
