So you are running Simple Review 3.0.10? The line numbers in your errors don't seem to match up with the code in 3.0.10.
Did you upgrade to 3.0.10? If so which version did you originally install? Did you apply EACH upgrade individually? The upgrades are incremental and you must upgrade them one-by-one e.g. 3.0.7->3.0.8->3.0.9->3.0.10
