VBA Macro ignoring "On Error Resume Next"

[MartinLBlood]

I have a macro that was running flawlessly until I added some simple code to hide and unhide certain rows. That part of the code works a intended. I have the statement "On error resume next" just before the statement "ActiveSheet.ShowAllData" to skip sheets that don't have filters (I'm looping through several sheets). Could I have messed up the normal macro calculation during the debugging process? I've checked the preferences an "Break on unhandled errors" is checked. During the macro, I turn off events.
Where should I look? Thanks in advance for your reply.

From the code you supplied, I can't see any errors.
