ToC broken after republish on site

 My best guess for the toc behaviour goes something like this:

* A week ago, "topic 1" was in toc1.js.

* You access the page and toc1.js is cached on the server (because you don't change your script files very often, right.)

* Two days ago, the content is updated, and now "topic 1" is in toc2.js

* You access the page, and the cached toc1.js is used rather than the correct toc2.js, so everything appears wrong because the wrong js file ha been slotted in to the toc.

Try getting your server administrator set a much shorter max age value for the http cache-control headers on the whxdata folder.

Specify that you only want to change the max age for that folder, not all js files on the server, because those files aren't traditional, static js files. 

>Is it feasible to autocreate a new TOC? 
I will try it, however, upload takes about 1.5 hour, so i'll do it later. We need our site to be reachable now. 
Also, we got 2 different ToCs. Without subcategories (sections and only topics inside) and with subcategories (section inside section). Both broken on site. 

>And it's working & looking correctly when you launch from that "local folder you used for upload"? If so, is there anything different about the server? Not just a plain old webserver?
Yes, everything is okay. I'm not responsible for the server, the only thing I know - this is not a plain webserver with only Robo on it. We also store a main site there.

And it's working & looking correctly when you launch from that "local folder you used for upload"? If so, is there anything different about the server? Not just a plain old webserver?

It could be a change on the server that is not allowing certain file types to run properly, I have seen that before.

Is it feasible to autocreate a new TOC? The structure will be wrong but if that works and your TOC does not, you can republish using the broken TOC so that you are no worse off in the short term. At least then you will know something about what is broken.

As I know there is no single ToC file, that I can check for correctness. ToC is controlled by a big amount of .js files.
I compared whole whxdata folder and its content using TotalCommander file comparison with local folder that I used for upload. All files are the same .

As @Jeff_Coatsworth says. I use Beyond Compare but there are various ways.

More like fire up an FTP client or File Explorer & look at the files that are behaving correctly on your local machine & the mis-behaving files on the server and see if any don't match.

Every upload we delete all content of the server folder, and only after this we upload the new content.
Yes, we tried comparison earlier.
To be clear: You mean upload files on the server, then download them back and compare with those which was uploaded?

I assume you have already tried deleting everything and uploading again. It does look like a corrupted upload. 

Did you try the server / local comparison?

Hi Peter.
This is not a new issue, however in past we observe only content (topics) missing  or old cached version. Now all topics in different sections and neither cache clearing,  nor new device (that never opened site before) helps.
Files are the same.
For now we haven't an ability to upload it to a different location in this server, but I will ask our team. 
A week has passed since the last update, but the ToC is still damaged
