This may be the first sanitization issue to come across related to the patches that are expected to be applied to all ZC 1.5.x but come mostly standard to ZC 1.5.5.a. Since that filename format is not one that I would typically use nor suggest, no testing was applied to it.
The version i used for old zencart 1.3.9 is Easy Populate 4.0.19 - Beta 1-28-2012,everything works fine.

Expecting updating to solve the problem for zencat 1.5.5a,thank you very much.
