I'm not sure what you're referring to. JavaScript isn't something you "upgrade" — if you're saying you upgraded Java on your system, that's something completely different and unrelated to Zotero.

Never did much javascript (even though I did work for Netscape back in the 1990s...) and am too long out of the coding game these days.

I think the upgrade to javascript did the trick ... it has been giving me the rotating sync circle for over 5 minutes ... a good sign I believe ( It may be catching up on syncing all my pdfs since I j

actually, when I clicked on the exclamation button (red), it is telling me it is 845084090... possibly javascript?

If you know some javascript, you could look at the code here:

I don't see us doing that — we'd focus on simply improving what you can do via the UI — but you can run arbitrary code in the Run JavaScript window and create/update a collection from a set of item id

[JavaScript Error: "Error: Only 0 translators present in cache. Resetting

[JavaScript Error: "Can't commit outside of transaction" {file: "chrome://zotero/content/xpcom/notifier.js" line: 313}]

[JavaScript Error: "S3 returned 0 (1/Z5SDYXK9) -- retrying upload"]

In your case, I would instead use the Zotero JavaScript console to batch edit items that have “books.google.com” in their URL field and replace that field with “”.

[JavaScript Error: "this.skipWords is undefined" {file: "Better BibTeX" line: 1305}]

[JavaScript Error: "Cannot change 'mtime' directly in group library" {file: "chrome://zotero/content/xpcom/sync/syncEngine.js" line: 1305}]

JavaScript Error: "Cannot change 'mtime' directly in group library" {file: "chrome://zotero/content/xpcom/sync/syncEngine.js" line: 1305}]

[JavaScript Error: "Win error 32 during operation remove on file C:\Users\[…]\Zotero\storage\N6D6IRFT\[…].pdf (The process cannot access the file because it is being used by another process.

While on that page, enter this in the JavaScript console and press Enter:

[JavaScript Error: "Discarding invalid field 'volume' for type 7 for item 1/null"]

In any case, can you open the JavaScript console and see what errors show up when you load the page?

No, it's not a general issue. [JavaScript Error: "File is not valid XML" {file: "chrome://zotero/content/xpcom/style.js" line: 629}]

The plugin is primarily written in JavaScript as part of the main Zotero app. VBA is only used as in interface to Word to control the buttons.
