We host are own site
I am again running into the same antelope to barracuda problems as I did when I set up a test site. I have seemingly tried all the recommendations with changes to the my.ini file running the script etc. I do believe there was a file i edited on the test site that fixed this problem but that was on iis this new site is apache xampp.
I created a new database and exported the sql from the old site and imported to the new database made all the changes to config.php and was able to start the install but got only to the Server checks page of the setup!
Been doing this for almost twenty years and this barracuda thing drives me nuts! Would really appreciate your help.
So the only thing that you have to fix is the intl extension which probably is not installed on your server and the innodb large prefix setting. If you have phpmyadmin installed you can find this setting in the variables section(you can also change antelope to barracuda here.) Change it there, restart your database server and reload the page to see if it will allow you to move on.
