The formatting is lost when editing text blocks

Permalink
Hello,
I have a page that has a large number of small blocks (343) that need to be edited either with a price change or colour change. When I had v8.0.2 this was possible but slow, now I have upgraded to v8.2.1 the formatting is lost and the page cannot be saved. Is it possible to correct this and speed up the editing process?

Can you provide a link to your site? It almost sounds like you have a javascript error on your page that's causing editing issues.

Hello hutman

Thank you for your response, this is the page that is the problem, at present this site is not live but running on my own server:

It looks like you have a javascsript error - 2018-rates:1020 Uncaught TypeError: Cannot set property 'innerHTML' of undefined

You should resolve that and see if it fixes your page.

Hello huntsman

Thank you for the reply, I am more a designer than a coder so I will get someone to look at that for me.
However I did notice that when the page is scrolled up there is a message: 'An unexpected error occurred Maximum execution time of 30 seconds exceeded' I presume that this is something to do with the number of blocks on the page.

I don't see that error, but that could certainly cause an issue too. Perhaps up the max_execution_time on your server to 60 seconds?

Hello hutman

Thank you for your help, the problem was resolved by increasing the execution time on my server. I don't suppose there is any way to speed up the time it takes to edit the blocks caused by the large number on the page?

I don't think the issue is the time that it takes to edit the block so much as it's the amount of time it takes to display the page. Would it be possible to move this functionality into the Dashboard somehow instead of adding individual blocks to the page?
