Hope you're okay! So very sorry to see the plugin won't be maintained but I hope I can still bother you with a question about it.
I have seen a drop in indexed urls on my site lately, and I just found out it has probably to do with this: pto_sitemap produces an xml with all the feeds, but all XML's in it give a Wordpress critical error page.
This Error page doesn't give a clue on what could be the problem (with all DEBUG's in wp-config on). In the standalone version of the site, the sitemap is created without problems.
I turned off the plugins, but still no go.
Do you have any idea what could be happening? Thank you!
With kind regards,
Sorry to say it's still the same error, except now the created XML's have a double //
I got brave and just uploaded a newer 2017 version of the sitemap, and now it's working! Could have tried this sooner, but I was thinking in Wordpress issues.
To correct this in this instance edit pto_sitemap.php and look for the following code at line 48:
$sitemapBaseHREF = get_bloginfo('url')."/";
...and REPLACE with:
$sitemapBaseHREF = get_bloginfo('url')."/".$pto_config_permalink;
