Hi, Renee.
Thanks for posting your question. I’m sorry to see that your site is displaying a fatal error rather than loading. If you are able to login to the admin dashboard, I recommend deactivating the plugin that is causing the error. This appears to be something related to “flexmls-idx” as indicated in the error/file path. Check with the developers of the Flexmls IDX plugin regarding that error and how to correct it. I hope this helps, feel free to comment if you have further questions or any persisting issues.
Sincerely,
Carlos E
