Membership. Response Error: PayPal did not verify this transaction: INVALID

I see this error in my Transaction Logs:
Response Error: PayPal did not verify this transaction: "INVALID

I'm from Brazil and when I get return from IPN the date comes with special characters like 'á' or 'ã'.
When I test without it it works fine.
I'm testing with the IPN simulator on PayPal developer's website.
The currency is BRL and country Brasil.

    Hi Daniel

    Hope you're having a wonderful day!

    In order to isolate the issue and make sure that it's not a result of a conflict with another plugin/theme, can you please do a plugin/theme conflict test?

    The simplest way to perform the test:

    * Switch theme to one of the default WordPress themes (ex., Twenty Seventeen)
    * Login to your site via FTP
    * Navigate to wp-content
    * Rename the plugins folder to _plugins
    * Create a new empty plugins folder
    * Move the plugin folder (ex: membership) you want to test from _plugins to plugins
    * Check if issue still persists, if no, proceed to the next step
    * Then, one at a time, move other plugin folders over from _plugins to plugins until the symptom returns

    NOTE: While you are doing this, do not visit WP Admin > Plugins on your site. This will ensure that your plugins remain active when you copy them back over.

    Let us know about results.

    Also, for further investigation, we will need FTP or cPanel access to the site. Could you send us your details through our contact form using this template (please DO NOT post any credentials here as it's a public forum):

    Subject: "Attn: Katya Tsihotska"
    -cPanel username
    -cPanel password
    -cPanel login URL


    -FTP credentials (host/port/username/password)
    -link back to this thread for reference
    -any other relevant URLs

    Please use this subject line to ensure that it gets assigned to me :slight_smile:

    Kind regards,

Thank NAME, for their help.
