Constant Contact Plugin not compatible with WordPress 4.8.2?

My hosting provider suggested trying an older version of the plugin. Is there a way to download an older version?

Hi Linda,

Without more detailed information about the error in question, it’s hard to pinpoint exactly what’s going on. “Error 500” is pretty generic and not any indicator that the issue is for sure Constant Contact. It is indicative, based on your feedback, that the error is occurring when Constant Contact Forms is active.

You can download previous versions of the plugin at the bottom of https://www.ads-software.com/plugins/constant-contact-forms/advanced/ but the last release we had was two months ago, which is well before version 4.8.2 from WordPress. Hard to say how many people may be using that combination, but I haven’t seen any come in for support.

Sorry, how can I get you more error info? where can I find it?

The hosting provider support should be able to help out there, especially if you’re no necessarily the most technical/developer-y (zero offense intended).

Any new developments with this one @lindamaybe2013 ?

I just installed the plugin and get a 500 error as well, also when attempting to edit a WP page while the plugin is active. From our logs:

@kurt-freshrrcom are you working from a windows or linux server at the moment?

The key part of the error shown is:

‘cURL error 60: SSL certificate problem: self signed certificate in certificate chain’

Basically there’s issues with the current SSL certificate not being accepted for some reason.

https://community.constantcontact.com/t5/Getting-Started-with-API-s/Fatal-error-Uncaught-exception-GuzzleHttp-Ring-Exception/td-p/266223

It’s a Linux server running NGINX. I can have IT look into it, but it’s curious that when the plugin is activated it also takes out /wp-admin/edit.php for editing pages, posts, etc.

Keep us informed, as I’d be interested in knowing what works to solve the issue, if a solution is found quickly.

Kind of one of those fatal errors that seems to occur no matter what screen you’re loading.

Hey @companyv

I recall one other person running into this same error, but I was unable to reproduce at the time. I requested that they try something I mention in this forum reply: https://www.ads-software.com/support/topic/fatal-error-when-using-php-7-1/#post-9358631 however I think something changed on their end that ended up no longer causing an error.

I am wondering if you could help try this change out while you’re still experiencing it.

The file in question should be in the /vendor/constantcontact/guzzlehtp/guzzle/src/utils.php location within our plugin, around line 144-145.

If you confirm that things are working afterwards, I’ll get this patched up for a future release.

As is, it looks like there is some sort of error occurring with the parsing/decoding of JSON for your current case.

@companyv Any feedback or followup for my questions and reply above?

Thanks.
