Please help me fix these asap as I am missing out on important emails.

Hi,

The message say the email didn’t had body content. Check the plugin log and you can see who sent it.

The lock file I check it.

It’s shared hosting ?

It is shared hosting, yes.

Here is a screenshot of the email log:

I am having the same issue as @timescapeireland. I am able to successfully clear the lock file but when I run the test again I get:

Sending the message: Ajax Error

@markmelch

You have php 5.4, not supported version.
Tell your host to upgrade.

And what about my issue, please?

Upgraded to 5.6 and now get:

Sending the message: Failed
Status: {
“error”: {
“errors”: [
{

Do I need to go to PHP 7?

The log shows:
{ “error”: { “errors”: [ { “domain”: “global”, “reason”: “failedPrecondition”, “message”: “Mail service not enabled” } ], “code”: 400, “message”: “Mail service not enabled” } }

Also FYI: www.ads-software.com/plugins/post-smtp/ still shows:
REQUIREMENTS
WordPress 3.9 and PHP 5.2 with SPL and iconv

Thanks for your plugin and support.

1. Login to your account, see if no messages show, everything ok.

2. Go to google console and check the gmail api is enabled.
