Yes, I tried Firefox (which is in English) and Internet Explorer, I didn't try Safari or any other browser but I thought that two would be enough. I tried at the office and one other location. Looking at the error log is a good suggestion but which one? Does wikipedia have an error log or do you mean the apache error log?
PHP error log. The errors may be logged by apache at its log, at another place stated at php.ini, or not logged at all and needing to be configured.
