1728 php_admin_value open_basedir /opt/joomla:/home/e-smith/files/primary/files/index:/home/e-smith/files/primary/html/phpgedview/index_new:/home/e-smith/files/ibays/outlook/files
AFAIK open_basedir is for directories and AFAIK they should all end with a trailing slash, which some of yours do not seem to do.
But that is after i edited a custom template, there was an newline after line 1728 'php_admin_value open_basedir' where line 1729 should directly after 'php_admin_value open_basedir'
Thanks a lot, you have us searching for a problem you have caused yourself but did not provide information on ...
Today my website is no longer responding. I can't find anything in the logs what could explain this.
... but you could have easily figured that out yourself by retracing your tracks... on top off that you did not even have the guts to provide the faulty fragment as to me it seems you pasted the fragment after fixing the error:
1728 php_admin_value open_basedir /opt/joomla:/home/e-smith/files/primary/files/index:/home/e-smith/files/primary/html/phpgedview/index_new:/home/e-smith/files/ibays/outlook/files
Thanks for the help you pointed me in the right direction 
I hope you learned from it, next time please be upfront with all information instead of giving it after we have traced your error... no shame in making mistakes.
