And now it seems resolved. I had an error when deleting and reuploading the products that said ‘must be an .xls or .xlsx file’. I had not seen this before. I saved the products spreadsheet as a new .xlsx file and uploaded that successfully. Now the sidebar is appearing normally.

Looking at it further this morning, it appears that for some reason in this catalog only, .prod-cat-container has a height of 0px. I don’t reference this class in my theme’s CSS anywhere, nor is it taking an inline style. Though I’m not sure if this is a symptom of the sidebar not appearing or a cause.

Using shortcode [product-catalogue id=’4′ sidebar=’yes’], but still not displaying the sidebar.

The sidebar is not appearing at all.

Ignore the lack of images- they are on my locahost only at the moment.

How strange. That seems to have done it. I haven’t changed the permalinks since I first set up the site.

<shrug> Ah well, whatever works!

Thanks kessiemeijer!

I’ve done the manual upgrade as described in the Codex, and the same problem remains (including the Cannot modify header information error).

I enabled WP_DEBUG and WP_DEBUG DISPLAY, and am now showing this additional error:

Warning: Cannot modify header information – headers already sent by (output started at /mydomain.com/wp-includes/class-wp.php:204) in /mydomain.com/wp-includes/pluggable.php on line 1178

I will try the manual update now (after reading the instructions)

Considering it took a month for you to reply, I’ve already found a solution by using another plugin.

Fixed!

Turned out it was some whitespace causing problems, both in config.php and in my parent theme’s functions.php.

Still no idea why it affected me on a live server but not on my localhost version.

Whatever, so long as it works!

By going to ../wp-login.php, I am able to login. It’s the dashboard that’s not showing up. Logging in seems OK.

At the moment, the only warnings I’m getting are plugin based:
Strict Standards:
Accessing static property advanced_code_editor::$tablename as non static in /home/lesliemc/public_html/wp-content/plugins/advanced-code-editor/advanced-code-editor.php on line 66

When I rename that plugin’s directory, to prevent WordPress from using it, I get no errors or warnings whatsoever, but the page displayed is blank, and the source contains only the contents of my child theme’s functions.php file.

I have also tried deleting that functions.php file (it was quite small and easily reconstructed once I can get the dashboard working). The result is still a blank page, no errors, but now showing no page source at all.

Ok, so after enabling DEBUG and DEBUG_DISPLAY, I see that there were PHP warnings regarding my child theme’s functions.php file. The contents of this file were what I was seeing when viewing the page source.

I deleted the file to see if that resolved the problem, but no such luck. Still a white page, with no viewable source at all. No errors displayed, no error log generated, and no page.

@thegreyparrots, that got me a login prompt, which seemed to be accepted, but then I was redirected to the same blank page.

What I can’t figure out is why this is happening after deployment, but not on the localhost development version (both are identical, I haven’t edited either one since deployment).

I even tried uploading multiple times, with the same problem. Which is why I’m now asking the wise forum-goers.

No font plugins anymore. I’m thinking this is a remnant of a plugin which I tried and have since disabled and deleted.

I’m just going to edit each post individually and delete the code. Frankly, I should have thought of that earlier. With the plugin gone, I’m assuming that new posts will not have this problem.

Thanks for all your help!

I’ve figured out that it’s an inline style that’s overriding less specific styling, but I don’t know where to find the code in question.
