Hi Tihana,
I have increased both from 15 minutes to 30 minutes.
Also, we have this in the htaccess file:
php_value upload_max_filesize 1024M
php_value post_max_size 128M
php_value max_execution_time 600
php_value max_input_time 600
php_value max_input_vars 4000
php_value memory_limit 1500M
Thanks for replying. I will see if that makes any difference, but I had one user yesterday who said the form failed to complete on 3 separate devices - using his Mac desktop, a PC desktop and a mobile phone... I tested again yesterday on my phone and the form submitted correctly in under 30 seconds including images!
