our website www.wolknlocations.com runs via Wordpress with the template Lay theme. I am building up a Newsletter via Mailchimp. Currently I would like to add a pop-up signup form on our website. It worked one time – but now it's only sometimes visible, and then again it's not visible anymore without any obvious reason. We have already tried different things like: deleting the cookies on the website / trying different browsers / users / laptops / etc. but nothing has helped so far.
I think it is probably a problem with Lay Theme. Have you experienced this problem in the past?
Thank you in advance!
