Hello,
I can see two problems in your page.
The first one is the management of the dates ; the starting date of the product has not been imported correctly.
That issue is coming from modification in the mijoshop structure but we are not aware of the version so it will be difficult for us to make a patch since we can't know if we need to import the raw data and convert it into a timestamp.
For more details about the requirement modification, you can check that forum post :
www.hikashop.com/forum/install-update/89...eld-list.html#275983
I suggest you to perform the modification of the mijo import and then try to perform a new import.
The second issue is related to the product description. I don't know why but it looks like the HTML content has been encoded so while HikaShop is displaying it (using the Joomla JHTML core helper), the HTML is not displayed as HTML but as raw text.
I have to admit that I don't know how it could happen since the import copy directly the data (so it would mean that the data is not stored correctly in mijoshop)
