Hey, I have a problem 
When I want to import a csv file with my contacts into the Contacts - import contact. After uploading the file and click next I see the message “your file is empty one”. What can I do with this?

Try this:
Locate the configuration file for MySql (normally it is called my.cnf or my.ini, but it depends on the implementation that you have).
Find the following variables:
. max_allowed_packets and increase the value to 500M
. increase to at least 300 seconds all the variables that contain “wait_timeout” at the end of their name and in case add also a variable called wait_time_out
You may also want to increase the values of net_write_timeout and net_read_timeout
Additionally you may want to increase your php.ini environment configuration variables:
max_execution_time = xx <-- try putting 3000
max_input_time = xx <-- 3000
max_input_vars = xx <— 10000
memory_limit = xx <— 500M
upload_max_filesize = xx <-- 256M
Please report back if it works
