Fatal error: Cannot redeclare class NumberFormatter in

Interesting! What other plugins do you have on your site?

That error indicates a naming collision between a component in this plugin and a component in some other part of your website. I would suggest disabling all plugins except Inline Google Spreadsheet Viewer, checking to ensure that error is not displayed, and then re-enabling them one at a time until this error returns. That way we can figure out where the collision happens.

Thanks for reporting this.

I deactivated every plugin except for yours and it didn’t change at all. I tried to do the regular Google spreadsheet one and even though I have it set to public, is says it is not found.

I really need the csv version to work. I can’t have this information where other people can see. The site is password protected to my contractors.

Any other ideas?

If there’s no other plugin active on your site then the issue is with some other code still running on your site. It might be in your theme (try temporarily changing to the default theme) or it might be some other incompatibility introduced by custom development.

If you are not the programmer of your website, consider speaking with whoever is responsible for the code of your site and asking them for more information about what they’ve added to your site. The fact that the incompatibility is not in a custom plugin is, frankly, worrying, because it means whatever modifications were made to your site were probably not made in a way that is easy to isolate, and thus harder to fix. ??

With no activity for a week, I’m considering this issue resolved.

Hi Meitar, i changed to the default theme and disabled all plugins however the same error persists.

<b>Fatal error</b>: Cannot redeclare class NumberFormatter in <b>D:\Var\www\html\wp-content\plugins\inline-google-spreadsheet-viewer\lib\visformat.php</b> on line <b>20</b>

Plugins that are not activated are still being loaded by the PHP interpreter. You may need to manually move a plugin out of the wp-plugins folder before the conflicting plugin is fully “deactivated.”

I did a virgin installation of wordpress. I installed only inline google spreadsheet viewer plugin. I uploaded a csv file. I created a post and put the shortcode [GDOC key = “https://localhost/portal/wp-content/uploads/sites/28/2015/10/test.csv”%5D.
Result:

<b> Fatal error </ b>: Can not redeclare class NumberFormatter in <b> D: \ Var \ www \ html \ wp mono \ wp-content \ plugins \ inline-google-spreadsheet-viewer \ lib \ visformat.php </ b> on line <b> 20 </ b>

Contents of my csv file:
test, “test”, “test”

In your case the fatal error is probably a PEAR or other included PHP package that defines a NumberFormatter class.

Basically, some other PHP code is being executed before WordPress, and loading a NumberFormatter class that is conflicting with the vistable library that this plugin uses.

But dont worked…

Hello Meitar!

I am also getting the same error:

Fatal error: Cannot redeclare class NumberFormatter in /wesp/atlantis/web/wp-content/plugins/inline-google-spreadsheet-viewer/lib/visformat.php on line 20

The only other plugin I am using is Embed any document
Ebed any document

I turned this off and removed it and it still shows up

have you been able to find the solution to this problem yet?

Yeah, it’s just a naming conflict with one of the libraries I’m using. Unfortunately I don’t really have the time or resources to invest in rewriting the library to fix the issue in the small number of cases where it crops up. My suggestion for now is the same as above: find out what other NumberFormatter class is being loaded and, if you don’t need it, disable it. If you do need it, you can remove or stub out the library where NumberFormatter is declared in this plugin, since this plugin’s NumberFormatter is only used when doing a query against a CSV file.

I found this in the PHP site:
https://php.net/manual/en/class.numberformatter.php
It seems they created a new class with the same name of yours. Could it be the cause of the conflict?
