Issue after last release

Hi,

we have a problem that seems to be related to your plugin.

After last release 5.2, we have problem to update the post: in some cases the loader doesn’t stop and updating we lost the edit version of the post.

In other cases, we get this error:

Error thrownCall to undefined function xmlsf_cache_get_archives()

We tried to install previous version of the plugin and everything come back ok.

Have you ever heard of this problem? I’m looking for a solution in google but seems an unknown issue.

Thanks for your help.
