Hi,
What kind of blank page do you have ? A page without HikaMarket content but with some HTML or a full white page ?
If it's a full white page, it could be a PHP error log and we will need to error message in order to know more about (PHP error log or using the "error reporting level" to "maximum" in your Joomla global configuration).

By the way, do not send me private message, use the "contact us" form instead.
