Please help me to figure out with following problem:
Start import some .csv file (about 200 records) -> Application starts importing records, successfully import about 20-50 records and on the some moment it redirects to the Dashboard page.. logs (application/apache) is empty..
disc space is available, max_execution_time=300, memory_limit=64M
I want to recommend you Store Manage for Magento for future imports. Its wizard is a perfect and very easy to use tool to perform export and import of products, categories, attribute sets and custom options.
