 * Hi [@monster695](https://wordpress.org/support/users/monster695/)
 * Thanks for reaching out! I’m sorry to hear that you are experiencing this issue.
 * Can you check out those errors within your CSS stylesheet and see if you are 
   able to identify where they are coming from?
 * Can you also link me to the page where you are seeing this issue? I wasn’t able
   to locate any issues on your site just yet.
 * I hope that helps!
 * Thanks,
    Jaime

 * Sorry, we disabled the plugin. There were various errors being reported using
   sortsite to test for accessibility issues. We are dealing with ADA compliance
   concerns (not specific to The Events Calendar but rather the entire website) 
   and needed to show as few issues as possible which led us to disabling the plugin.
