 * Thanks, I found and fixed the cause of the fatal error (“Cannot access offset
   of type string on string” in Collector.php:939). The patch validates the variable
   before accessing offsets and has been deployed.
 * Please update the plugin to the latest version and clear any caches/OPcache. 
   If the error continues, reply with the plugin version and the full error trace
   and I’ll investigate further.
