3 zen cart websites (1= V1.51 and 2 are V1.39) will need an ONE TIME age verification pop-up before they can browse the site .
I would prefer a css html float popup simliar to hegre-art (dot) com (NOT WORK SAFE LINK!!!)
The pop-up must not interfere with spider and bot crawling that way the SEO doesn't get affected.
The pop-up must load on every page, but once it is clicked YES once, it must not load again until the visitor clears their cookies.
The pop-up window needs to be 600 x 600 and I will need to be shown how to edit the HTML that loads in the pop-up.
Somebody ready to that ?
I can create a one-time verification. It will display once per session, (or 1 day timeout / browser session). It will not affect your SEO or bot visibility in any way. I can show you how to modify it as well :)
