Addition to previous message
I will try to explain better what I discovered yesterday morning.
1) all the equations of the Equation Editor to wordpress TinyMCE editor, Version 1.5 by ‘modalweb’ were replaced by the orange banner ‘Invalid Equation’.
2) Pressing the banner, the equation window was correctly shown, but closing the window
the banner remained.
3) I checked the text source of the visible page and of course it looked unchanged.
4) The defects lasted until the afternoon when progressively (not at the same time) disappeared, that is some equations returned visible while other remained replaced by the banner.
5) This morning, CET, March 12, and now all equations look visible without banner
Question: what did occur? The Italian provider aruba.it denies any problems in their computer system. Is it true? I do not know.
My impression is some difficulty (may be a time out in the plugin or elsewhere?) in converting text into visible equations. I cannot go further, but I would like to know the reason and how to prevent for the future by myself and provider.
