site I'm developing suddenly not working on iPhone 5… but was yesterday

Hi – I’ve been using Enfold for awhile now & LOVE it! I just downloaded v. 3.4 & am doing the pre-development of a new site on my own hosting server, after which I’ll be purchasing another copy of Enfold for my client.

My issue is this: yesterday the site I’m working on came up fine on my iPhone 5, but suddenly today I’m continually getting the Safari message “Safari cannot open the page because the server cannot be found”. However, it opens fine on my Mac in Safari.

I have another Enfold site on the same hosting server & it still comes fine today on iPhone 5… but it’s an older version of Enfold.

Some deets:
– The ONLY change (other than content) I made since yesterday was to deactivate some unused plugins that I had used for other sites previously designed on that test server. None of these were being used in the current site.
– I’m in Mexico right now, and another friend here tried on his iPhone 5 today, also to no avail. My internet is working fine (I’m accessing internet thru wifi on my iPhone) HOWEVER, another friend here tried it on her Android phone and it came up fine… ???
– the site comes right up on my Mac, both in Safari & Chrome.
– My GoDaddy hosting plan is NOT WordPress-optimized. However, the other Enfold site on there works fine on iPhone.
– I’ve tried everything… clearing my Safari data on iPhone 5 & updating to latest OS version, rechecked all Enfold settings, etc…

Once the initial site design is complete, I will be moving the real site to a different domain, on a WordPress-Optimized GoDaddy server. However, I want to be sure I’m not going to have the same issue there, as the mobile version of this is highly crucial.

Any chance you can help?

Thanks in advance!
Susan
