Answer 1

All errors are related to VES_pdfpro and VES_core.

If you have already cleaned all Cache(s) you may want to restart PHP in order to remove any opcode cache (like APC or op_cache).

Anyway, seems to be a cache or a partial uninstallation issue so please check if you have some templates and/or layout.xml files in the code.
