The admin log shows me in Dutch:
(A requested parameter is not (correctly) entered: src)CGSmartImage Een verplichte parameter is niet (correct) ingevuld: src
IMO it would be helpfull if the admin log also would show where it discovered the error or on what the notification is based. I think it would save time in investigating the cause of the notification shown.
In the above case, I search where I use CGSI, looked at the parameters, they all have either src or src1, and sometime src1 and src2 -no src-, so at the moment I have no clue what is causing the notification. I expect CGSI wants src, src1, src2, meaning one has to start with src and not with src1 when one has several src-parameters.
