Hang on, let me check . . .
$generate_cache_at_upload is not in any of my tfu_config files.
Actually, I have several config files. I'm not sure which one gets used and they list different software versions:
admin/tfu_config.php (TWG Flash uploader 2.7.3)
admin/upload/tfu_config.php (TWG Flash uploader 2.10.x)
admin/upload/my_tfu_config.php (no version)
i_frames/tfu_config.php (TWG Flash uploader 2.7.3)
I'll try adding it to the my_tfu_config.php file in admin/upload . . .
Nope, that didn't help. Did I add it to the wrong one?
I uploaded two files. They uploaded, but TFU had an error: Upload failed. 2 file(s) of 2 could not be uploaded. The cache files were created when I refreshed the page.
One other thing, occasionally when I click the upload link I get an error: "You are not logged in. Please go to the main page and log in properly". I don't see it very often, but I've seen it twice while running the above test.
I logged into TWG, navigated to a subdirectory, clicked upload and got the error. I clicked logout then clicked login and entered my username and password. I ran this upload test, typed in my findings here, went back, closed the TFU window, clicked the upload button again and got the login error.
Maybe related? There's also that EXIFreader error.
Does this help?
