For several operations I get an errormessage. For example when I try to copy a dbfield of a catalog, or try to create a number field. The errors are SQL messages always starting at "maxValue ....". To deal with the problem for now I renamed the maxValue field to mxValue in the database (which already got rid of the message), and I changed every appearance in the PHP code to mxValue. This patched the problem.
It seems MAXVALUE is a reserved word for MySQL:
MAXVALUE is used to represent the least upper bound for the type of integer in question. -MAXVALUE represents the greatest lower bound.
