I am having the same issue. Does anyone have any thoughts on how to fix this?

hello both

does this happen exclusively when changing the currency?

It also happens when I add Default invoicer data

Hello, I updated Invoice Manager to 4.0.1
Now I can add Default invoicer data BUT I still can't use Mexican pesos or many other currencies, the component work with Euros or US Dollars and it doesn't work with multiple currencies.

I have the same problem. But with me it happens when I edit anything and save it. It keeps saving...

I should mention that I use Joomla 4 & PHP 8.1

Turning debug system on and error reporting to none "solved" the problem.

If you’re encountering issues where you can’t create a new invoice after changing any options, it sounds like there might be a problem with the software's configuration or a potential bug. Here are a few steps you might consider to troubleshoot:

Check for Updates: Ensure that your invoicing software is up-to-date. Sometimes, these issues are resolved in newer versions or patches.

Review Options: Double-check the options you’re changing. Ensure that the settings are compatible and that you haven’t selected any options that could conflict with each other.

Error Messages: Look for any error messages or alerts that might give you more details about why the invoice creation is failing.

Reset Settings: If possible, try resetting the options to their default settings and then attempt to create a new invoice again. This can help determine if a specific option is causing the issue.

Software Support: Contact the support team of the software you’re using. They may be able to provide specific guidance or troubleshooting steps based on their knowledge of the system.

Check Permissions: Ensure that you have the necessary permissions to create invoices and that there are no restrictions in place that might be blocking this action.

If the problem persists, providing specific details about the software you’re using and the exact nature of the options being changed might help in diagnosing the issue more precisely.
