Honored ContributorI am using 8.0 SP1 web edition and I ran into this bug today after specifying a new Signal Tap file. This bug definitely has something to do with Signal Tap as it did not appear until after I added the new Signal Tap file today. I have been successfully using Signal Tap with this project for some time.
I removed the offending Signal Tap file from the project and disabled Signal Tap, but Quartus still refused to compile. Since you cannot access the incremental compilation settings in the web edition, setting incremental_compilation to off in the QSF file was the only way I could get Quartus working again. I've read somewhere that the web edition of Quartus does allow incremental compilation of Signal Tap changes, so it must be getting confused where to allow it and where not to. If this is true, then I suspect that I may want to comment the incremental_compilation line in the QSF once Quartus is well again, otherwise all minor Signal Tap changes will require a complete and lengthy recompile.
