Many undefined array and deprecated warnings when adding a new activity for a contact
- Open a contact and go to the "Activities" tab
- Click on "+ New Activity"
In many case we see a lot of warnings appearing in watchdog - in total 21 but it seems that the following 3 messages are repeated 7 times:
Warning: Undefined array key "params" in include() (Zeile 5 in C:\wamp64\www\civicrm\httpdocs\sites\default\files\private\civicrm\templates_c\en_US\%%DF\DF0\DF0B0562%%RecurringEntity.hlp.php)
Warning: Trying to access array offset on value of type null in include() (Zeile 5 in C:\wamp64\www\civicrm\httpdocs\sites\default\files\private\civicrm\templates_c\en_US\%%DF\DF0\DF0B0562%%RecurringEntity.hlp.php)
Deprecated function: strtolower(): Passing null to parameter #1 ($string) of type string is deprecated in smarty_modifier_lower() (Zeile 23 in C:\wamp64\www\civicrm\vendor\civicrm\civicrm-packages\Smarty\plugins\modifier.lower.php)
For the last warning: I mentioned it already in #4312 - maybe this warning might be an issue on it's own
