Several things going on here... One, you have PHP 5.4 with ZC 1.3.9h... Possibly part of the problem... In fact, the ZC team is trying to at least keep 1.5 running on PHP 5.4...
Next a potentially low Memory limit.
Then there is the editor that is being used, as it may not be compatible with the above configuration, so..
Recommendation overall is to upgrade it all, also in the mean time, if not able to use an editor that converts things such as We'll send the product out right away into something like We'll send the product out right away.. Then to be sure that the text to be applied is html safe...
There may also be some updates offered in the forum to support ZC 1.3.9h to run under PHP 5.4, but it would require some research.
Thanks for your response which I have passed on to our web brain cell to investigate.
TBH I couldn't get my head around how something SW based could work for years fine and then suddenly not work without anything changing so I was convinced that the issue must be something changing on the Mac I use. So I used a different to no avail. So then I tried a Windows machine and that was exactly the same! Now I thrown away my skepticism along with everything I thought I knew...
Thanks again for suggestions. If I get any firm conclusions I'll post back in the hope that others may find it useful!
