Some users are unable to click the start re-enrollment form link because it isn't selectable; when the mouse hovers over the link, the cursor treats it like regular text or any other section of the web page.
This issue can be caused by design problems, specifically another section/element of the page, like a logo with a set size, covering up the hyperlink's set location on the page. Blackbaud support recommends testing issues using a blank layout, blank template, and blank page to see if design is the root cause. This can be confirmed by through the use of Google Chrome developer tools to inspect page elements to see if any are overlapping or by disabling styling/page elements.
Note: The editing and designing of your website is beyond our scope of support. Consult with a qualified web developer or your account manager for information on Blackbaud services.
