Greetings, Many of those errors, I have been working on submitting patches as I run into them in areas I am working on. As the other response said they aren't a significant concern, except for floody logs (which I thoroughly deplore and aim to fix every chance I encounter them while working).

See the warning in "Fetching the value or values of a single named parameter" at /usr/share/perl5/CGI.pm line 436." I was searchig for the warning, and it seems that mainpage.pl in koha-common needs to be fixed, but I don't know how. Or perhaps there is other way avoid the error. REgards and thanks in advanced
