Pardon me if my responses are as lazy as your questions:
1. Hang while bulk import,
When i import the products, it hangs after importing 65 or 66 records.
Split your spreadsheet into 2 or 3 spreadsheets and see if you can repeat the problem. Export all products and re-import, if it stops at 65 or 66 again, then the problem is with Magento, otherwise it is your spreadsheet.
2. remove the footer of front page,
My frontpage has footer like
Help Us to Keep Magento Healthy - Report All Bugs (ver. 1.1.4)
Footer is located in a few places. In admin, select “CMS>Static Blocks”, select “footer links” and modify that as needed. Another is located in “System>Configuration>Design.” Search for the one that mentions “keeping magento healthy” in the forums and you’ll find the answer.
3.bulk import categories witthout creating first,
Do i have to create the category first and then link in the csv file.
Canât i just import the categories without creating first i.e just entering the category name in the csv file for bulk import.
to add categories in bulk you need to:
1. create categories in admin
2. import products (enough to represent each category).
3. assign each category to 1 unique product.
4. export all products and determine which category goes where.
5. plug that into your csv and re-import.
This process should be improved in the near future, but is not among the more vital fixes they are working on. Photoshop didn’t have the “history” feature until v4 so who’s complaining?
4. How to make category theme same as frontpage
I have installed the modern theme for frontpage.
How can i change the feel and look of the category page.
Select your category, select “Custom Design” tab
choose the layout that matches your home page (2 column, 3 column, etc).
You will then realize you need to learn how to use static blocks for your category pages to add content between the top and the products. You can also remove products from category and add them via the static blocks. I suggest you watch the screencast for Static Blocks, it’s one of the few screencasts still working.
Otherwise, I suggest using search before asking too many more questions, and the more time you take to ask a question, the better response you will get from those who know the answer.
