I’m sorry to hear about the uploading issues! Here are a few questions for you that will help me troubleshoot this for you:
restart the browser and try to log in again? Sometimes that kicks things into gear. To do this: http://help.zenfolio.com/customer/portal/articles/408028
2. What browser type and version are you using?
Can you please try it on a different browser such as Firefox or Chrome? Does it still have issues? 3. Can you please try disabling any antivirus software that you may be using and see if that helps? Sometimes overly strict security settings can block some site functionality.
4. What are the file type and sizes and how many are you trying to upload? Does it work in smaller batches? 5. Are you using a wireless router? What happens if you connect directly to the wired connection?If you are at an office or behind strict security filters you may want to see if they can be bypassed for your Zenfolio site as this may be causing some of the photo uploads to fail.Also, if you are on a wireless router, you may want to have it restarted or connecThere are many different types of security settings, filters, firewalls, and proxy servers. Unless you speak with the network administrator at your clients' offices, there would be any way for you to know what is causing the problem.
It is likely not a content problem and it is more likely that the security settings do not allow sites with complex transactions to make through their encryption levels without being bypassed.
