Hi, and thank you so much for your reply. It's so funny coz I was going to reply and found your message.
indeed, the solution is to create the .htaccess file, found it here: [external links are visible to admins only]
It'll be nice if you can add it to the Doc
I'm currently facing another issue, when I click on "Run", it crawls the urls but stops after few minutes, do you know why?
and what about the used memory, does it get freed up when the crawl is finished?
For info, memory_limit: 120Mo and max_execution_time: 50000
