several customizing in the CRM system Vtiger 5.4.0

I have following tasks to offer: - fix an error message in the vtiger settings/ backup server: Fatal error: Out of memory (allocated 51904512) (tried to allocate 31491304 bytes) in /homepages/10/d118456930/htdocs/vtiger_5.4.0/include/db_backup/Source/[login to view URL] on line 150 - fix an error in the calender of Vtiger: in the view of "month" the week starts with Tuesday - in the view of "month" I like to see the details of a term. At the moment I only see the time f.e. " 09:00 - 15:30". But I like to see the details in the overview f.e. "Important Meeting with XY". This could be also realized by a mouse hover / tooltip solution. - customize the default print forms for Quote and invoice (simple customizations, mainly translations of english expressions to given german expressions) - fix an error message that occurs after saving a sales order: Warning: Illegal offset type in /homepages/10/d118456930/htdocs/vtiger_5.4.0/include/utils/[login to view URL] on line 2902 Warning: Illegal offset type in /homepages/10/d118456930/htdocs/vtiger_5.4.0/include/utils/[login to view URL] on line 2902 Warning: Cannot modify header information - headers already sent by (output started at /homepages/10/d118456930/htdocs/vtiger_5.4.0/include/utils/[login to view URL]) in /homepages/10/d118456930/htdocs/vtiger_5.4.0/modules/SalesOrder/[login to view URL] on line 68 - fix a bug: EMails "CC" and "BCC" will not be sent. Only direct selected Contacts get Mails. - if a workflow-email to a contact was sent successfully there is no information about this happening. Normally the regarding EMail is assigned to the contact. - if I want a notification for a new term, the emails will be sent twice. - if I create a new term the time in the month overview has one hour delay Regards Hannes
