Hi Leigh,
Not likely that the issue was created via changes in SLP, or we would most likely have heard an awful lot of complaints by now and the testing is fairly robust. I am guessing it has something to do with your CSS rules or theme,. Having said that, sometimes bugs are revealed that we are unaware of since there are so many combinations of unique settings and site configurations out there.
I can have the developer take a look when he can but he is working on two paid customization projects at the moment so I am not sure when he can get into looking at your site.
If you want to provide some login credentials and get on his schedule ASAP you would need to go through the Paid Support. If it is a bug on SLP’s part we of course would not charge you the support fee,. To get on his schedule to troubleshoot your site, please opt in for the level of Paid Support. you feel you need.
