    Hi David,

    Zip as uploaded contains managed server log, report server logs/trace will be different. Refer to How to Enable Reports Engine/Server/Servlet/Zrclient Trace in Reports 12c (Doc ID 2070743.1) to get detail trace ( trace of level NOTIFICATION:16) for report server which is executing your report and failing with REP-1800.

    REP-1800 is generic error and is usually followed by next error code which gives more detail as what could go wrong with "formatter" engine. For example, could be a font issue, large complex report, shortage of runtime memory ( virtual memory as managed by buffers parameter) .

    Once you generate detail report server trace, check if it points to anything specific.
