PHP Errors from Pdb_Session.php file

  • First, let me say how much this plugin is loved – it has allowed for the management of over 100 volunteers amazingly…. until this week. Our host shut down the site temporarily until they could figure out what was pulling 80% of the servers resources, once they were able to narrow down the plugin they removed permissions and deactivated and are now asking that I delete, what will happen! The plugin was generating Cron jobs? every 60 seconds – here are a few of the last few lines from the error log file on the server: `[11-Mar-2021 17:30:59 UTC] PHP Warning: Cannot modify header information – headers already sent in /home…..wp-content/plugins/participants-database/classes/PDb_Session.php on line 322

    We updated to the most recent version of WP and did upgrade the PHP version on the server to see if that would help but it didn’t. Any ideas? TIA!

    I can’t see what the real problem is in the logs yu provide, these are all just the effects of another problem. “Headers already sent” suggests that some other plugin (or perhaps your theme) initiated output early, which prevents the session from being initiated. You need to find out which plugin is misbehaving.
