Unsucceessful first calculator launch

User Dmytro Sapolovych 2025-11-16 16:13:30

Hi guys,
I was trying to make a simple sample calulcator using excel file without any php / js code but didn't succeed at all.

1) First after I set up my sample there was no action after I push the Calculate button. At the same time in the Chrome's console I found 1 error: "Failed to load resource: the server responded with a status of 500 ()" (deeper research showed the comment - Content unavailable. Resource was not cached.

At the same time there were no any other details. The web server error logs also did not record a detailed 500 error.

2) I had to contact my hosting provider to find out the issue source. 'cos I thought its affiliated with the server restrictions. But the first thing the support guy saw was an error page (please see the screeenshot attached.). I beleive it appears when several people are trying to open the link at the same time. Cos it's happend to me when I was trying to open the link from my laptop and phone within 30 seconds: it is ok from laptop and an error on my phone.

Hi,

We've checked your calculator and there were only 2 issues in Spreadsheet configuration:

- First sheet number is 0 instead of 1.
- The input field name should be Days instead of Daysnum

With these adjustments the calculator shows the output properly.

Please let us know if you need further help.

Thanks. Regards,

Moonsoft Team

Thank you guys, the first one was my bad.

But the second thing still appears... This one - 0 Unsatisfied dependency "cb_preinit" for an asset "cb_jquerymigrate" of type "script"

It appears when I open the link from more then 2+ devices. Any suggestions?

Any ideas?

Hi,
that error is not thrown by the extension, seems your site or server is avoiding multiple loading of the scripts, which is quite strange. Probably is related to a wrong handling of the cache, because we found you have active the site cache, while the cache plugin is disabled. With the cache plugin enabled, the error disappears.

Hope this helps,
