Deprecated Warning with GiveWP: str_contains() and str_replace() Errors in PHP 8

Hi everyone,

I’m encountering a deprecated warning when I install the GiveWP plugin on my site running PHP 8. Here are the specific errors:

Deprecated: Return type of Money\Currencies\AggregateCurrencies::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in wp-content/plugins/give/vendor/moneyphp/money/src/Currencies/AggregateCurrencies.php on line 66

Deprecated: Return type of Money\Currencies\ISOCurrencies::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in wp-content/plugins/give/vendor/moneyphp/money/src/Currencies/ISOCurrencies.php on line 64

Deprecated: Return type of Money\Currencies\BitcoinCurrencies::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in wp-content/plugins/give/vendor/moneyphp/money/src/Currencies/BitcoinCurrencies.php on line 43

Deprecated: Return type of Money\Currency::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in wp-content/plugins/give/vendor/moneyphp/money/src/Currency.php on line 86

Deprecated: Return type of Money\Money::jsonSerialize() should either be compatible with JsonSerializable::jsonSerialize(): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in wp-content/plugins/give/vendor/moneyphp/money/src/Money.php on line 521

These warnings appear to be due to deprecated return type compatibility in the moneyphp/money library that GiveWP uses, especially with PHP 8 and above.2.

“Form is Not Published” Error

When I try to add the shortcode for my published form, I get an error saying that the form is “not published” even though the form is definitely set to “Published” in the GiveWP dashboard. I’ve checked the following:

• Form Status: I verified that the form is published (not in draft or scheduled mode).
• Correct Shortcode: I’m using the correct shortcode format for the form ID, like [give_form id="1234"], where 1234 is the form’s actual ID.

I’ve tried the following troubleshooting steps:

• Confirmed that WordPress and GiveWP are both up to date.
• Checked my PHP version (currently PHP 8.0).
• The warnings do not appear when GiveWP is deactivated.

I’d appreciate any guidance on:

1. Whether others have encountered this with GiveWP in PHP 8.
2. Any suggested fixes or workarounds (e.g., PHP version compatibility, settings adjustments, or suppressing warnings).
3. If this is something that needs to be reported to GiveWP directly.

Thanks in advance for your help!
