Unwanted changes on the homepage

All of a sudden I noticed some strange changes on the homepage and I found this message on dashboard: Trackback on July Field Meeting 2020 Report [Pending] Homepage ... [Trackback] [...] Find More Informations here: andaluciabirdsociety.org/field-meeting-reports-sp-1182534073/july-field-meeting-report/ [...] These are the changes: Links are no longer visible. The blue color and underlining has disappeared. The homepage, which is a static page now shows a empty right column. The footer is showing now next to the copyright info the following text: NEW_LOGO_FINAL_WEB_BANNER_EDITION | FOTOGRAFIE BLOG BY CATCH THEMES Can you help me to solve this?
