Hi apcherry and thanks for the response.
I should have mentioned that the errors with the package manager is when trying to install any package not just the google sitemap.
These problems are preventing me updating any packages whatsoever. I don’t know if it’s related but if I add the googlesitemap-1.2.1-pl package directly to the core/packages folder and run the Add New Package >> Search Locally for Packages functionality, it does not pick up the plugin from their either.
Looking in the modx_transport_packages database table, I can see entries that have null value as follows:
'getresources-1.3.1-pl', '2011-07-18 11:23:44', NULL, NULL, 1, 1, 1, 0, 'getresources-1.3.1-pl.transport.zip', NULL, NULL, 'getresources', 'a:31:{i:0;a:4:{s:4:"name";s:2:"id";s:10:"attributes";a:0:{}s:4:"text";s:24:"4d556c3db2b083396d000abe";s:8:"children";a:0:{}}i:1;a:4:{s:4:"name";s:7:"package";s:10:"attributes";a:0:{}s:4:"text";s:24:"4d556c3db2b083396d000abe";s:8:"children";a:0:{}}i:2;a:4:{s:4:"name";s:12:"display_name";s:10:"attributes";a:0:{}s:4:"text";s:21:"getresources-1.3.1-pl";s:8:"children";a:0:{}}i:3;a:4:{s:4:"name";s:7:"version";s:10:"attributes";a:0:{}s:4:"text";s:5:"1.3.1";s:8:"children";a:0:{}}i:4;a:4:{s:4:"name";s:13:"version_major";s:10:"attributes";a:0:{}s:4:"text";s:1:"1";s:8:"children";a:0:{}}i:5;a:4:{s:4:"name";s:13:"version_minor";s:10:"attributes";a:0:{}s:4:"text";s:1:"3";s:8:"children";a:0:{}}i:6;a:4:{s:4:"name";s:13:"version_patch";s:10:"attributes";a:0:{}s:4:"text";s:1:"1";s:8:"children";a:0:{}}i:7;a:4:{s:4:"name";s:7:"release";s:10:"attributes";a:0:{}s:4:"text";s:2:"pl";s:8:"children";a:0:{}}i:8;a:4:{s:4:"name";s:8:"vrelease";s:10:"attributes";a:0:{}s:4:"text";s:2:"pl";s:8:"children";a:0:{}}i:9;a:4:{s:4:"name";s:14:"vrelease_index";s:10:"attributes";a:0:{}s:4:"text";s:2:"pl";s:8:"children";a:0:{}}i:10;a:4:{s:4:"name";s:6:"author";s:10:"attributes";a:0:{}s:4:"text";s:8:"opengeek";s:8:"children";a:0:{}}i:11;a:4:{s:4:"name";s:11:"description";s:10:"attributes";a:0:{}s:4:"text";s:150:"This release fixes a few small bugs in the way the criteria is built for resources and tvFilters properties, as well as allows a 0-based idx property.";s:8:"children";a:0:{}}i:12;a:4:{s:4:"name";s:12:"instructions";s:10:"attributes";a:0:{}s:4:"text";s:37:"<p>Install via Package Management</p>";s:8:"children";a:0:{}}i:13;a:4:{s:4:"name";s:9:"changelog";s:10:"attributes";a:0:{}s:4:"text";s:333:"<p></p><p style="margin-bottom: 15px; ">getResources 1.3.1-pl (July 14, 2011)</p><p style="margin-bottom: 15px; "></p><ul style="margin-bottom: 15px; "><li><li>[#43] Allow 0 as idx property</li><li>[#9] Fix tvFilters grouping</li><li>[#46] Fix criteria issue with &resources property</li></li></ul><p></p>";s:8:"children";a:0:{}}i:14;a:4:{s:4:"name";s:9:"createdon";s:10:"attributes";a:0:{}s:4:"text";s:23:"2011-07-14 21:11:48 UTC";s:8:"children";a:0:{}}i:15;a:4:{s:4:"name";s:10:"created_by";s:10:"attributes";a:0:{}s:4:"text";s:8:"opengeek";s:8:"children";a:0:{}}i:16;a:3:{s:4:"name";s:8:"editedon";s:10:"attributes";a:0:{}s:8:"children";a:0:{}}i:17;a:4:{s:4:"name";s:10:"releasedon";s:10:"attributes";a:0:{}s:4:"text";s:23:"2011-07-14 21:11:48 UTC";s:8:"children";a:0:{}}i:18;a:4:{s:4:"name";s:9:"downloads";s:10:"attributes";a:0:{}s:4:"text";s:5:"24646";s:8:"children";a:0:{}}i:19;a:4:{s:4:"name";s:8:"approved";s:10:"attributes";a:0:{}s:4:"text";s:4:"true";s:8:"children";a:0:{}}i:20;a:4:{s:4:"name";s:7:"audited";s:10:"attributes";a:0:{}s:4:"text";s:4:"true";s:8:"children";a:0:{}}i:21;a:4:{s:4:"name";s:8:"featured";s:10:"attributes";a:0:{}s:4:"text";s:4:"true";s:8:"children";a:0:{}}i:22;a:4:{s:4:"name";s:10:"deprecated";s:10:"attributes";a:0:{}s:4:"text";s:5:"false";s:8:"children";a:0:{}}i:23;a:4:{s:4:"name";s:7:"license";s:10:"attributes";a:0:{}s:4:"text";s:5:"GPLv2";s:8:"children";a:0:{}}i:24;a:3:{s:4:"name";s:7:"smf_url";s:10:"attributes";a:0:{}s:8:"children";a:0:{}}i:25;a:4:{s:4:"name";s:4:"name";s:10:"attributes";a:0:{}s:4:"text";s:12:"getResources";s:8:"children";a:0:{}}i:26;a:4:{s:4:"name";s:10:"repository";s:10:"attributes";a:0:{}s:4:"text";s:24:"4d4c3fa6b2b0830da9000001";s:8:"children";a:0:{}}i:27;a:4:{s:4:"name";s:8:"supports";s:10:"attributes";a:0:{}s:4:"text";s:3:"2.0";s:8:"children";a:0:{}}i:28;a:3:{s:4:"name";s:10:"screenshot";s:10:"attributes";a:0:{}s:8:"children";a:0:{}}i:29;a:3:{s:4:"name";s:4:"file";s:10:"attributes";a:0:{}s:8:"children";a:7:{i:0;a:4:{s:4:"name";s:2:"id";s:10:"attributes";a:0:{}s:4:"text";s:24:"4e1f5b96f2455409d900006c";s:8:"children";a:0:{}}i:1;a:4:{s:4:"name";s:7:"version";s:10:"attributes";a:0:{}s:4:"text";s:24:"4e1f5b94f2455409d900006a";s:8:"children";a:0:{}}i:2;a:4:{s:4:"name";s:8:"filename";s:10:"attributes";a:0:{}s:4:"text";s:35:"getresources-1.3.1-pl.transport.zip";s:8:"children";a:0:{}}i:3;a:4:{s:4:"name";s:9:"downloads";s:10:"attributes";a:0:{}s:4:"text";s:3:"458";s:8:"children";a:0:{}}i:4;a:4:{s:4:"name";s:6:"lastip";s:10:"attributes";a:0:{}s:4:"text";s:15:"188.112.246.192";s:8:"children";a:0:{}}i:5;a:4:{s:4:"name";s:9:"transport";s:10:"attributes";a:0:{}s:4:"text";s:4:"true";s:8:"children";a:0:{}}i:6;a:4:{s:4:"name";s:8:"location";s:10:"attributes";a:0:{}s:4:"text";s:60:"http://modx.com/extras/download/?id=4e1f5b96f2455409d900006c";s:8:"children";a:0:{}}}}i:30;a:4:{s:4:"name";s:17:"package-signature";s:10:"attributes";a:0:{}s:4:"text";s:21:"getresources-1.3.1-pl";s:8:"children";a:0:{}}}', 1, 3, 1, 'pl', 0
Any help would be much appreciated.
Thanks in advance.
