Strange errors after updating concrete

Permalink
Greetings,

Ever since we did an update on a client’s site we are getting some really strange errors - the errors give no relevant info, just repeat text on the page. I notice a error_log file in the root directory and it is referencing this:

[24-Jan-2015 09:39:22] PHP Warning:  strpos() [<a href='function.strpos'>function.strpos</a>]: Empty delimiter in /home/firstref/public_html/updates/concrete5.6.3.2/concrete/core/libraries/request.php on line 72


Was there an error with the update? The errors are very random, You can make several site updates before they pop up. Any help is appreciate, if more info is needed please ask! Thanks in advance C5 wizards.
