Log gets filled with error
Bug #49251 is still present. Since I cannot reopen this bug I create a new one.
In current version 1.11.0, the log is filled with errors:
Invalid argument supplied for foreach() in <path>/typo3conf/ext/ods_osm/pi1/class.tx_odsosm_pi1.php on line 127
I guess a simple default value for marker_popup_initial is missing in the tsconfig.
