We are glad to know that you considered using Basel for your web-site. I hope you will be happy with it.
Could you please test how a default WordPress import works? You can try it in Dashboard -> Tools -> Import. Take any XML file for import from the folder inc/dummy-content.
If it works but doesnโt work on our Dummy Content section then please provide us your FTP access so we can fix it.
We meant that you can check WordPress default import with any of the XML files there. You don’t need to import them all manually. Just check is it our theme issue or the import function doesn’t work in your WordPress installation at all.
Sorry, but we can’t check the problem and help you to fix it while we don’t have an access to your website. Probably, there is some issue with your server configuration.
I had the same problem and I solve it. You should increase max_execution_time and max_input_time in your php.ini
For example:
max_execution_time = 86400
max_input_time = 86400
After changes in php.ini dont forget to restart the server (apach or ….)
