Hi Nigel
Thanks for your response, much appreciated. We're aware it's a mess. We're currently rebuilding the back end from scratch, which will solve the structural problems but completion is 6 months away.
We've checked htaccess, it's not that. We have rel canonical on almost everything to fix the issue where pages show for the wrong URLs etc, it’s not ideal but fixing it is a massive job given we just need to keep it going another 6 months. We want to avoid work we will be throwing away, unless there are big wins.
Whilst communicating this to you my developer has found a fix. He said 'I’ve had to regenerate some of the SVGs, looks like someone got creative with now they built the SVG, I’ve now taken out all the creativity and hard coded the data into them.'
So it sounds very site specific.
thanks again Nigel - I've now clocked Carousel Projects UK.
