 * Our host provider updated to 7.2 recently, and it is causing deprecation issues
   with all our plugins and making it so that navigating to agsgerbils.org brings
   you a blank page (typing in the https:// manually worksaround this for now).
 * The specific error we get that relates to PDB is this:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/agsgerbi/public_html/wp-content/plugins/advanced-classifieds-and-directory-
   pro/widgets/search/class-acadp-widget-search.php:187) in /home/agsgerbi/public_html/
   wp-content/plugins/participants-database/vendor/wp-session-manager/class-wp-session.
   php on line 142
 * The plug-in has been deactivated at time of writing, I am not sure when it will
   be up again.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fphp-7-2-13%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * First, make sure you are using the latest version of Participants Database.
 * Really (and I hate to say this) the cause of the problem is the other plugin…
   looks like some kind of search widget, it’s outputting to the screen too early
   which is interfering with other plugins. It may be that that other plugin is 
   outputting an error that you are not seeing. Anyway, I’d suggest deactivating
   that other plugin and see how it goes. Check with the developer about compatibility
   with php 7.2

 * Replying to this as a person working on the same website. I reached out to our
   host provider today and we found that the caching plugin Hummingbird was affecting
   the errors. We have since removed that plugin for now.
 * I checked and we do have the latest version of Participants Database. Now on 
   the website we are consistently receiving this error at the top of every page
   on the website:
 * `Warning: Cannot modify header information - headers already sent by (output 
   started at /home/agsgerbi/public_html/index.php:1) in /home/agsgerbi/public_html/
   wp-content/plugins/participants-database/vendor/wp-session-manager/class-wp-session.
   php on line 142`
 * Not sure what this means. Can you help us resolve this issue? Thanks!

 * What that means is that on that script, at the very top, is some character (probably
   space) before the <?php tag. Take that out, so that the <?php tag is the the 
   first thing in the script.
