Steven:
Thank you for your reassuring comments about that extra semicolon in JavaScript.

I have found another error which may be stopping SFTP from loading the theme.css properly.

There is a HTML coding error in the Juicebox jbcore/theme.css.
The fault is in lines 200, 201, 202 and 1181.

I have made the corrections myself in the Juicebox jbcore theme.css file for each Gallery; and the JB Galleries have now all loaded correctly on the iPower.com server and are displaying from my website.
Fixing this code does seem to matter when the gallery is part of a folder that is part of  a website.

If anyone else runs into problems with JB Galleries not loading in websites, correcting this may help.

The jpcore was apparently loaded — but when i opened it I found it had no contents! 
That may be the clue to the mystery?

I will let you know what I discover but at least I know now that Juicebox is not the culprit.

@Steven:
Thank you for your very helpful response to my post.

Just a thought, but is there anyway to make Juicebox work in a different space than in Desktop?

iCloud is not allowed into my "Pictures" files so perhaps there is a way to make Juicebox Builder use that area by default?

Doing that in the web browsers has fixed it! Thank you so much Steven.

Making those browser Settings changes is something that I should have thought of!
I had fresh installations of Mac OS, Safari and Firefox on the MBPro and hadn't thought to see if their settings had been changed.

The files do load correctly on my web site through FileZilla Pro.

Steve:

Thank you for your very quick response.
You suggested exactly the right remedy: Rosetta!
I had entirely forgotten that requirement for JuiceBox.

I had recently installed M1 Macs and had migrated all my files and apps over to them but the Rosetta setting did not come over.

I have now got JBPro running on one M1 Mac and will now go and make the change to Rosetta on the other one.

Thank you again for your invaluable help.

Ann

Both Macs will now run JBPro!!

I haven't noticed much slowness but, while JBPro does work on M1 Macs by going through Rosetta, the real long-term (and expensive!) fix would be to rewrite JBPro to work natively with the M1 Macs — and with M2 ones too.

Apple will not return to Intel and the JBPro software is much too valuable to lose.

To follow-up on the AIR issues:

I followed your advice and wiped all parts of both JuiceBoxPro and AIR completely off all of my Macs. Doing that has resolved nearly all of the problems which I was experiencing.

The real key turned out to involve removing every particle of Harman AIR from the machines (by using their Uninstaller) before loading their latest version of AIR.

I followed the total removal of all things AIR with  making clean installation of JBPro.

The result is that:

I can now insert multiple files from the Image Panel’s Browse for images.

JBPro now populates the Images Panel very quickly again.

Galleries will Save to default the 'juicebox_gallery' directory.

The Save/Browse button does now shows the “New Folder” button again but if I open "Browse" I still get a Freeze so this issue obviously still awaits a fix from Harman.

The Config issue was being caused by a Browser setting (which I have now fixed as I described in another topic).

So JBPro is now entirely workable again for now in both Mac OS Mojave and in Monterey — just as long as I don't hit that "Browse" button in the Save area.

The comments here provided the vital clue to solving my problem with a missing Config!

A new installation of Safari had somehow changed my Prefs so I was not seeing the "Develop" tab in Safari's Menu Bar.

In Safari's Prefs., Advanced must be checked;
and the "Show Develop Menu . . . " item then needs to be checked as well.

The user of Safari must then check the item "Disable Local File Restrictions".

Unless this is done, JBPro Galleries will not open locally and you will get the "Config file not found" error message.

Steven:

These are the notes that I made while I tried various remedies:
>>>>
Deleted ELS
Then JBPro did indeed Save to a default gallery to a folder named 'juicebox_gallery'
As you said, the name can then be changed in the Finder

However, the Freeze returned if I hit Browse from the Save Panel.

I then Downloaded the new version from Harman Air and installed the new Frame work.

Got error message referencing an “Unsigned” application

Re-ran the “for Catalina” Terminal fix which was successful

New ELS has re-appeared automatically

Unfortunately, I can no longer insert multiple files from the Image Panel’s Browse for images. I could do that previously.

JBPro became very slow to populate the Images Panel: it was very quick previously.

File will Save to default 'juicebox_gallery' but Browse button no longer shows the “New Folder” button

Trashed existing JBPro .plist

I then shut down the computer and rebooted.

On trying to open an existing Gallery with JBPro I was getting “no Config found” errors although the Config is definitely present.

Unfortunately it seems that I may have de-stabilized my copy of FBPro entirely with these experiments?!

I do have a TimeMachine Back-up so I tried to revert my installation of JB Pro.

Unfortunately, that has not worked completely because I cannot yet Browse for images and multi-select images from a folder of JPGs;
and there is now no “New Folder” box being shown if, in the Save Panel, I hit the Browse button.
Both of those were definitely available previously.

I probably will need to do a fresh install of JB Pro but I think that it might be wise if I wait for Harman's final runtime Fix before doing that?

I could easily be mistaken but either the Gallery Folder box was grabbing its data from a  Gallery Name; or I am sure that I must have been able to edit the text in the Folder box because I don't remember having to Browse to save a new Gallery with a distinctive name.

I feel that the User should be able to do that.

I have been getting frequent freeze-ups when opening a new window through the Browse button.

The only way to Cancel out of the freeze is by Force Quitting from JuiceBox which, of course, loses the entire Gallery which I have just built.

I think that the Gallery-naming issue is one which the Developers should want to address in the next version?

Newer operating Systems are almost certainly going to require updated Applications so I really hope that the Developers are working on a new edition of JuiceBox Pro because it is software on which I depend!
