Cannot change style/theme after 1.5.2 upgrade

[wagwag]

Hi,
I just upgraded my blog from Serendipity 1.4 to 1.5.2 and the only problem I see is that when I go to Manage Styles in the admin interface I get a plain while page (no css/images/formatting) with no listing of styles or any way to change the style; only the following text:

Theme/Style options

This theme/style has no specific options. To see how your template can specify options, read the Technical Documentation on http://www.s9y.org about "Configuration of Theme options".
Select the template you wish to use for your blog

Trying to open URL package_template.xml...
Fetched 233594 bytes from the URL above. Saving file as /var/www/templates_c/package_template.xml...
Data successfully fetched.

I looked at the source of this page and found it is not even a complete HTML page; it's just a chunk of HTML:

Code: Select all

<h3>Theme/Style options</h3><p>This theme/style has no specific options. To see how your template can specify options, read the Technical Documentation on www.s9y.org about "Configuration of Theme options".</p><h3>Select the template you wish to use for your blog</h3><br />
<div class="serendipityAdminMsgNotice"><img style="width: 22px; height: 22px; border: 0px; padding-right: 4px; vertical-align: middle" src="/templates/default/admin/img/admin_msg_note.png" alt="" />Trying to open URL <a href="http://netmirror.org/mirror/serendipity/package_template.xml">package_template.xml</a>...</div>
<div class="serendipityAdminMsgSuccess"><img style="height: 22px; width: 22px; border: 0px; padding-right: 4px; vertical-align: middle" src="/templates/default/admin/img/admin_msg_success.png" alt="" />Fetched 233594 bytes from the URL above. Saving file as /var/www/templates_c/package_template.xml...</div>
<div class="serendipityAdminMsgSuccess"><img style="height: 22px; width: 22px; border: 0px; padding-right: 4px; vertical-align: middle" src="/templates/default/admin/img/admin_msg_success.png" alt="" />Data successfully fetched.</div>
<br /><br />

The blog and the admin interface seem to be working fine otherwise. I've tried clearing browser cache and using a different browser, and deleting templates_c/* but none of that made any difference. I'm using the plain-vanilla style currently if that is relevant.

Any ideas?

Hi!

Usually this happens when PHP runs out of RAM, and PHP is configured to not display errors. You can try to edit your .htaccess and place "php_value display_errors On" into it to see errors. If it's really a RAM issue, you can try to edit .htaccess with "php_value memory_limit 32M" for example; if that doesn't work you might need to contact your provider to raise the memory limit.

XML parsing for plugins/templates goes heavy on the RAM. If you can'T raise the limit, you need to disable spartacus and upload plugins/templates manually.

You were exactly right. PHP errors are not displayed and the memory limit had been set to 12MB, but just a little more was needed because it worked fine set to 13MB. I went a ahead and set it higher though to avoid this problem in the future.

Thanks, Garvin!
