Topic on Project:Support desk

Hi, I just upgraded my wiki to 1.26. I followed the normal procedure --- extract the files, copy over "LocalSettings", "images", and "extensions", and then plop all that in the right place on the server. Then I ran the database schema upgrade procedure.

Everything seems to be working except the styles are all gone. When I check the output of load.php, I see this at the top:

/*
Internal error

Internal error

Problematic modules: {
    "mediawiki.sectionAnchor": "error",
    "skins.vector.styles": "error"
}
*/

...followed by some additional CSS that applies only to printing. (@media print { ... )

I checked the PHP error log and there is nothing interesting.

Where do I begin to check on what the problem is? Thanks.

Just to note, not using any funny themes, just the default "vector".

This error occurs on PHP 5.5 and PHP 5.6

It does not occur on PHP 5.4

I am using PHP 5.6. 5.4 has been EOL for a few months.

If this is a known issue, I guess I will wait for a fix in a later version. Things are working fine since I reverted back to 1.25.x.

Can you check (and maybe post) the output of the `<?php phpinfo();` Are there any restrictions in place?

At least one version of this issue has been asked on Stack Exchange:

http://serverfault.com/questions/743898/mediawiki-not-displaying-style-internal-error/744059

There could be other causes of this condition, however, as it really just says that Vector (the skin) could not be loaded successfully.
