Hi NetizenRon,
I solved this problem by this easy programming steps:
1. Point your browser to https://your-site/wp-includes/js/tinymce/tiny_mce_config.php
2. If is there a bunch of strange characters is because compression is working on the server:
– Go to line 173 of “tiny_mce_config.php” and where it’s said:
‘compress’ => false changes into ‘compress’ => true
– Try again in your browser:
The browser must show a plain javascript file in text format.
If not shown, and you have HTML code with warnings, just change line 20: $path = realpath($path); into $path = @realpath($path);
It worked for me after doing all the cache staff people tell me to fix and I was desperate about this problem.
