Hi Robin,
"Timestamp" are a way to say "Time stamped on file",
so, date/time seems to change according to Cumulus web updates,
for the file wt_data_inc.php. But your page is always displaying:
Parse error: syntax error, unexpected T_STRING in /home/u/u7423976/www/wt_data_inc.php on line 595
This looks like a file not processed by Cumulus. Check to see that you've
ticked option "process?" for that file... or take a fresh copy of that file
if error persist.
Regards,
Jacques
