Sitemap PHP error

I've just noticed that my site maps haven't been running since I moved server. I get the following error:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 57961301 bytes) in /home/baby/public_html/vbseo_sitemap/vbseo_sitemap_functions.php on line 1298

I have PHP memory set to 64mb and only 30,000 urls in each xml. Any idea?

Hello Stewart ,

Please try disabling Yahoo Text format sitemap option. It will be deprecated in vBSEO Sitemap Generator 2.6 as Yahoo now supports xml sitemaps.

All sorted, thanks Mert. I deleted the old sitemaps and re-ran the generator. Must have been getting stuck somewhere while overwriting.
