[Solved] Preview Tab Window Is Blank

[KitchM]

While I don't always use it, preferring to see the whole web site as it is, sometimes it is nice to use the Preview tab when editing a page.

However, I have notice recently that this tab window is always blank now. I cannot figure out how to turn it back on.

I am using version 1.11.10, with PHP 5.3.3 and Apache 2.2.15.

It might be also useful to note that there is no WYSYWYG display either. I removed MicroTiny and installed TinyMCE. (I did this after the problem developed, and would rather have that editor anyway.) There was no change.

I don't know if this helps, but there it is.

You should make a look to the server logs what's wrong.

You are using a lot of modules. And one of the important informations is not shown. Right, I mean php memory limit.

Have not checked your constellation but I think you need 128 MB memory to get this working without any trouble.

[KitchM]

I have 1.5 GB of memory on my server, if that was what you meant.

[chandra]

I meant the memory value assigned to PHP, not server memory ...

[KitchM]

Ah, that's different then.

I did find this one my server, if it helps:
Memory and transfer limit options
Maximum memory allocation 128M
Maximum HTTP POST size 10M
Maximum file upload size 10M

Does this help?

[chandra]

Are there any relevant outputs with debug option in config.php, activated php error reports and /or server logs?

[KitchM]

Alright. I did some research under other forums and found something interesting. It appears that there is a mixed content problem going on, and specifically it appears that there are places where TinyMCE is being called from an http:// address instead of an https:// address.

However, I can't seem to find where the insecure link is contain in any file, so I can't fix it.

[chandra]

Do you are using https for your website / admin?

Is the error gone if you switch back to http?

[KitchM]

There is no way to switch out of the secure web page. It always goes back to https.

[KitchM]

I could sure use more help on this. Especially as to finding any error logs.

Thanks.

years ago i found this snippet in a forum (probably this one)

Code: Select all

if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']=='on') {
  $config['root_url'] = $config['ssl_url']; 
}

which caused the preview to break. after i learned how to properly write a htaccess redirect i dropped that line and things are better since.

[KitchM]

Thank you for that.

Where would one find that code? Does one just remove it or change a setting? Is it created by a part of the admin settings?

Thanks again.

[rotezecke]

No, I had added this code manually years ago to my config.php file (and since removed it). if you haven't done so, this idea just hit a dead end.
