Piwik 1.3 Fatal error: Selecting date range

when we select a date range (to / from) we get the following errors. This does not happen every time but seems to happen more over larger time scales

Fatal error: Out of memory (allocated 30146560) (tried to allocate 4718674 bytes) in example.com/analytics/piwik/plugins/SiteSearch/ExtendedDataTableRow.php on line 35

we are on a shared host and don’t have access to the php.ini file

I will ask our host if we can increase the memory allocated to PHP
