Same issue for us with Line 559 in version 3.7.7
We do not have that issue with 4.2.2 (for Craft 4)

@joeforfuture If you're able to upgrade the site, you might be able to get past that.

I think this PR tried to address it, if I am reading it right, but has been un-merged for many months. #458

Same issue when navigating directly to /sitemap.xml.

• Craft version: 3.9.13
• ether/seo version: 3.7.7
• PHP version: 7.4.33

yii\base\ErrorException: Cannot use ::class with dynamic class name in /project/vendor/ether/seo/src/services/SitemapService.php:559
Stack trace:

Hi, we've got the same issue

Craft Pro 3.9.13
PHP version: 7.4.21
Seo: 3.7.7

Confirm that the PR #474 fixes the issue, is this or another fix going to be released soon?

@Tam Please help

We've just spotted this issue too. How am I able to utilise the fix by @cloetensbrecht in the short-term? Is that possible?

[garycrane]

Do I change my composer.json file?

from "ether/seo": "3.7.7",
to "cloetensbrecht/seo": "??.?.?",

Sorry, not had to do this before. Any advice greatly appreciated.

I managed to get a version of #479 fix running, but it only seems to render top level sitemap.xml correctly. The child sitemaps (/sitemap_sections_1_0.xml) look broken to me (not outputting any XML markup).

When I create sitemap, am facing error https://tutivsoft.com/ Hope this is fixed :-)

Thank you cloetensbrecht for the fix. I am already loading a modified copy of this plugin in our project repo due to another change that I had to make, so including your fix was easy.

It would be great to get his pull request approved in order to fix this properly.
