Errors like this usually are a result of moving a mysql database from one server to another. MySql table names are really only case sensitive on linux not on windows but often windows installations of mysql are configured to force all lower case table names. If a database is moved from an installation configured one way to an installation configured the other way it can result in errors like this.
I'm not seeing any errors in my scripts
/Setup/applications/mojoportal-core/SchemaInstallScripts/mysql/126.96.36.199.config create the table like this:
CREATE TABLE `mp_AuthorizeNetLog`
So the upgrade script 188.8.131.52 is correct and uses the same case that the table was created with. On linux it should match the case correctly, on windows it is not case senstive
