I'm having trouble updating pages. If I add:

6th – 11th SEPTEMBER. Quarr Abbey sees the return for our last exhibition of the year. Opening hours are 10.30am to 4.30pm.

to my home page and then click 'Update' the whole page goes blank.

I can add other text and it's OK. I've tried creating a test page and adding only the above line - it doesn't save the text.

Does anybody know what's going wrong here?

More info please: Where do you add that? What Zenphoto release? Errors in the server error log?

I'm adding the text to my home page, which is a ZenPage, url: http://www.ventnorbotanicalartists.org.uk/

I have discovered that if, when I update and the editor goes blank, I navigate away (say to Overview) and back again, the original text reappears, plus the first 3 characters of the text I've just pasted in. So I see '6th'. I also find than if I type the information, bit by bit, I can get up to 'SEPTEMBER. Quarr' - any more and I loose it.

Details reported on Overview page:
Zenphoto version 1.2.9 [5088] (Official Build)
Current gallery theme: vbaazenpage2 (modified ZenPage theme)
PHP version: 5.2.0-8+etch16
Graphics support: PHP GD library 2.0 or higher
PHP memory limit: 96M (Note: Your server might allocate less!)
MySQL version: 5.0.32

I checked the log that ZenPhoto keeps but last entry was some months ago so I reset it. Got the following messages:
Warning: chmod() [function.chmod]: Operation not permitted in /var/www/vhosts/ventnorbotanicalartists.org.uk/httpdocs/zp-core/admin-logs.php on line 21

Tried again to update the page, and failed again. Nothing appears in the Zen log.

Below - today's lines from my server error log:

Please upgrade. We cannot support such old version as 1.2.9 is. Sorry.

OK - thanks - I'll give that a go
