I am using v5-Nano (5.3?) I think I may have stumbled upon the problem. In looking at the logs I see: - PHP Warning: PHP Startup: mbstring: Unable to initialize module\nModule compiled with build ID=API20090626,TS,VC6\nPHP compiled with build ID=API20090626,TS,VC9\nThese options need to match\n in Unknown on line 0 How can I change the compiler? There are other similar errors for other module startups in the log file.
