We apologize but the legacy builder isn't supported any more on technical issues, only billing related matters.
I recommend that you'd transfer the license and domain to a site created under our newer builder - https://www.imcreator.com/. The service is completely free.
To transfer the domain to the newer builder - First, make sure to create your XPRS account and XPRS site (we cannot transfer an IMC site to XPRS). Once your XPRS site is ready, let us know, and we’ll move your premium license from your IMC site to your XPRS account.
Make sure to send us the following information:
A) Your IMC username
B) Your domain name
C) Your XPRS username
D) Your XPRS site's name or VBID
