I’ve tried the following settings and Design Cloud items are failing to install:
allow_url_fopen = On
upload_max_filesize = 512M
post_max_size = 512M
max_execution_time = 300
max_input_time = 300
max_allowed_packet = 16Mb
innodb_log_file_size = 128mb
So far I’ve tried Batteries Included and Crafty theme. It makes an attempt but then fails with alert.
